You can use Cytoscape.js for graph analysis and visualisation.</p><p>Cytoscape.js allows you to easily display and manipulate rich, interactive graphs. Because Cytoscape.js allows the user to interact with the graph and the library allows the client to hook into user events, Cytoscape.js is easily integrated into your app, especially since Cytoscape.js supports both desktop browsers, like Chrome, and mobile browsers, like on the iPad. Cytoscape.js includes all the gestures you would expect out-of-the-box, including pinch-to-zoom, box selection, panning, et cetera.</p><p>Cytoscape.js also has graph analysis in mind: The library contains many useful functions in graph theory. You can use Cytoscape.js headlessly on Node.js to do graph analysis in the terminal or on a web server.</p><p>Cytoscape.js is an open-source project, and anyone is free to contribute. For more information, refer to the <a href="https://github.com/cytoscape/cytoscape.js">GitHub README</a>.</p><p>The library was created at the <a href="http://thedonnellycentre.utoronto.ca">Donnelly Centre</a> at the <a href="http://www.utoronto.ca/">University of Toronto</a>. It is the successor of <a href="http://cytoscapeweb.cytoscape.org/">Cytoscape Web</a>.</p><h2 id="introduction/packages">Packages <a href="#introduction/packages"><span class="fa

for Cytoscape.js and Cytoscape is provided by NRNB (U.S. National Institutes of Health, National Center for Research Resources grant numbers P41 RR031228 and GM103504) and by NIH grants 2R01GM070743 and 1U41HG006623.

It supports directed graphs, undirected graphs, mixed graphs, loops, multigraphs, compound graphs (a type of hypergraph), and so on.</p><p>We are regularly making additions and enhancements to the library, and we gladly accept <a href="https://github.com/cytoscape/cytoscape.js/issues/new">feature requests</a> and pull requests.</p><h2 id="notation/architecture-amp-api">Architecture &amp; API <a href="#notation/architecture-amp-api"><span class="fa fa-bookmark"></span></a></h2><p>There are two components in the architecture that a developer need concern himself in order to use Cytoscape.js, the core (i.e. a graph instance) and the collection. In Cytoscape.js, the core is a developer’s main entry point into the library. From the core, a developer can run layouts, alter the viewport, and perform other operations on the graph as a whole.</p><p>The core provides several functions to access elements in the graph. Each of these functions returns a collection, a set of elements in the graph. Functions are available on collections that allow the developer to filter the collection, perform operations on the collection, traverse the graph about the collection, get data about elements in the collection, and so on.</p><p><span class="important-indicator"></span> Note that a collection is immutable by default, meaning that the set of elements within a collection can not be changed. The API returns a new collection with different elements when necessary, instead of mutating the existing collection. This allows the developer to safely use set theory operations on collections, use collections functionally, and so on. Note that because a collection is just a list of elements, it is inexpensive to create new collections.</p><p><span class="important-indicator"></span> For very performance intensive code, a collection can be treated as mutable with <a href="#eles.merge"><code>eles.merge()</code></a> and <a href="#eles.unmerge"><code>eles.unmerge()</code></a>. Most apps should never need these functions.</p><h2 id="notation/functions">Functions <a href="#notation/functions"><span class="fa fa-bookmark"></span></a></h2><p>There are several types that different functions can be executed on, and the variable names used to denote these types in the documentation are outlined below:</p><table><thead><tr><th>Shorthand</th><th>Works on</th></tr></thead><tbody><tr><td><code>cy</code></td><td>the core</td></tr><tr><td><code>eles</code></td><td>a collection of one or more elements (nodes and edges)</td></tr><tr><td><code>ele</code></td><td>a collection of a single element (node or edge)</td></tr><tr><td><code>nodes</code></td><td>a collection of one or more nodes</td></tr><tr><td><code>node</code></td><td>a collection of a single node</td></tr><tr><td><code>edges</code></td><td>a collection of one or more edges</td></tr><tr><td><code>edge</code></td><td>a collection of a single edge</td></tr><tr><td><code>layout</code></td><td>a layout</td></tr><tr><td><code>ani</code></td><td>an animation</td></tr></tbody></table><p>By default, a function returns a reference back to the calling object to allow for chaining (e.g. <code>obj.fn1().fn2().fn3()</code>). Unless otherwise indicated in this documentation, a function is chainable in this manner unless a different return value is specified. This applies both to the core and to collections.</p><p>For functions that return a value, note that calling a singular — <code>ele</code>, <code>node</code>, or <code>edge</code> — function on a collection of more than one element will return the expected value for only the first element.</p><h2 id="notation/object-ownership">Object ownership <a href="#notation/object-ownership"><span class="fa fa-bookmark"></span></a></h2><p>When passing objects to Cytoscape.js for creating elements, animations, layouts, etc., the objects are considered owned by Cytoscape. Objects like elements have several levels to them, and doing deep copies of those objects every time they are passed to Cytoscape creates additional expense. When desired, the dev can copy objects manually before passing them to Cytoscape. However, copying is not necessary for most developers most of the time.</p><h2 id="notation/gestures">Gestures <a href="#notation/gestures"><span class="fa fa-bookmark"></span></a></h2><p>Cytoscape.js supports several gestures:</p><ul><li>Grab and drag background to pan : touch &amp; desktop</li><li>Pinch to zoom : touch &amp; desktop (with supported trackpad)</li><li>Mouse wheel to zoom : desktop</li><li>Two finger trackpad up or down to zoom : desktop</li><li>Tap to select : touch &amp; desktop</li><li>Tap background to unselect : desktop</li><li>Taphold background to unselect : desktop &amp; touch</li><li>Multiple selection via modifier key (shift, command, control, alt) + tap : desktop</li><li>Box selection : touch (three finger swipe) &amp; desktop (modifier key + mousedown then drag)</li><li>Grab and drag nodes : touch &amp; desktop</li></ul><p>All gesture actions can be controlled by the dev, toggling them on or off whenever needed.</p><h2 id="notation/position">Position <a href="#notation/position"><span class="fa fa-bookmark"></span></a></h2><p>A node’s position refers to the centre point of its body.</p><p>There is an important distinction to make for position: A position may be a <em>model</em> position or a <em>rendered</em> position.</p><p>A model position — as its name suggests — is the position stored in the model for an element. An element’s model position remains constant, despite changes to zoom and pan. Numeric style property values are specified in model co-ordinates, e.g. an node with width 20px will be 20 pixels wide at zoom 1.</p><p>A rendered position is an on-screen location relative to the viewport. For example, a rendered position of <code>{ x: 100, y: 100 }</code> specifies a point 100 pixels to the right and 100 pixels down from the top-left corner of the viewport. The model position and rendered position are the same at zoom 1 and pan (0, 0).</p><p>An element’s rendered position naturally changes as zoom and pan changes, because the element’s on-screen position in the viewport changes as zooming and panning are applied. Panning is always measured in rendered coordinates.</p><p>In this documentation, “position” refers to model position unless otherwise stated.</p><p>A node’s position can be set manually, or it can be set automatically using a <a href="#layouts">layout</a>. Because the positions of two nodes influence the lengths of the edges in between them, a layout effectively sets edge lengths.</p><h2 id="notation/elements-json">Elements JSON <a href="#notation/elements-json"><span class="fa fa-bookmark"></span></a></h2><p>Examples are given that outline format of the elements JSON used to load elements into Cytoscape.js:</p><pre><code class="lang-js">cytoscape({

You can use Cytoscape.js for graph analysis and visualisation.</p><p>Cytoscape.js allows you to easily display and manipulate rich, interactive graphs. Because Cytoscape.js allows the user to interact with the graph and the library allows the client to hook into user events, Cytoscape.js is easily integrated into your app, especially since Cytoscape.js supports both desktop browsers, like Chrome, and mobile browsers, like on the iPad. Cytoscape.js includes all the gestures you would expect out-of-the-box, including pinch-to-zoom, box selection, panning, et cetera.</p><p>Cytoscape.js also has graph analysis in mind: The library contains many useful functions in graph theory. You can use Cytoscape.js headlessly on Node.js to do graph analysis in the terminal or on a web server.</p><p>Cytoscape.js is an open-source project, and anyone is free to contribute. For more information, refer to the <a href="https://github.com/cytoscape/cytoscape.js">GitHub README</a>.</p><p>The library was created at the <a href="http://thedonnellycentre.utoronto.ca">Donnelly Centre</a> at the <a href="http://www.utoronto.ca/">University of Toronto</a>. It is the successor of <a href="http://cytoscapeweb.cytoscape.org/">Cytoscape Web</a>.</p><h2 id="introduction/packages">Packages <a href="#introduction/packages"><span class="fa

The following organizations help develop Cytoscape:</p><p><a href="http://www.systemsbiology.org">ISB</a> | <a href="http://www.ucsd.edu">UCSD</a> | <a href="http://cbio.mskcc.org">MSKCC</a> | <a href="http://www.pasteur.fr">Pasteur</a> | <a href="http://www.agilent.com/">Agilent</a> | <a href="http://www.ucsf.edu/">UCSF</a> | <a href="http://www.unilever.com">Unilever</a> | <a href="http://www.utoronto.ca">Toronto</a> | <a href="http://portal.ncibi.org/gateway/index.html">NCIBI</a> | <a href="http://nrnb.org">NRNB</a></p><h1 id="notation">Notation <a href="#notation"><span class="fa fa-bookmark"></span></a></h1><h2 id="notation/graph-model">Graph model <a href="#notation/graph-model"><span class="fa fa-bookmark"></span></a></h2><p>Cytoscape.js supports many different graph theory usecases. It supports directed graphs, undirected graphs, mixed graphs, loops, multigraphs, compound graphs (a type of hypergraph), and so on.</p><p>We are regularly making additions and enhancements to the library, and we gladly accept <a href="https://github.com/cytoscape/cytoscape.js/issues/new">feature requests</a> and pull requests.</p><h2 id="notation/architecture-amp-api">Architecture &amp; API <a href="#notation/architecture-amp-api"><span class="fa fa-bookmark"></span></a></h2><p>There are two components in the architecture that a developer need concern himself in order to use Cytoscape.js, the core (i.e. a graph instance) and the collection. In Cytoscape.js, the core is a developer’s main entry point into the library. From the core, a developer can run layouts, alter the viewport, and perform other operations on the graph as a whole.</p><p>The core provides several functions to access elements in the graph. Each of these functions returns a collection, a set of elements in the graph. Functions are available on collections that allow the developer to filter the collection, perform operations on the collection, traverse the graph about the collection, get data about elements in the collection, and so on.</p><p><span class="important-indicator"></span> Note that a collection is immutable by default, meaning that the set of elements within a collection can not be changed. The API returns a new collection with different elements when necessary, instead of mutating the existing collection. This allows the developer to safely use set theory operations on collections, use collections functionally, and so on. Note that because a collection is just a list of elements, it is inexpensive to create new collections.</p><p><span class="important-indicator"></span> For very performance intensive code, a collection can be treated as mutable with <a href="#eles.merge"><code>eles.merge()</code></a> and <a href="#eles.unmerge"><code>eles.unmerge()</code></a>. Most apps should never need these functions.</p><h2 id="notation/functions">Functions <a href="#notation/functions"><span class="fa fa-bookmark"></span></a></h2><p>There are several types that different functions can be executed on, and the variable names used to denote these types in the documentation are outlined below:</p><table><thead><tr><th>Shorthand</th><th>Works on</th></tr></thead><tbody><tr><td><code>cy</code></td><td>the core</td></tr><tr><td><code>eles</code></td><td>a collection of one or more elements (nodes and edges)</td></tr><tr><td><code>ele</code></td><td>a collection of a single element (node or edge)</td></tr><tr><td><code>nodes</code></td><td>a collection of one or more nodes</td></tr><tr><td><code>node</code></td><td>a collection of a single node</td></tr><tr><td><code>edges</code></td><td>a collection of one or more edges</td></tr><tr><td><code>edge</code></td><td>a collection of a single edge</td></tr><tr><td><code>layout</code></td><td>a layout</td></tr><tr><td><code>ani</code></td><td>an animation</td></tr></tbody></table><p>By default, a function returns a reference back to the calling object to allow for chaining (e.g. <code>obj.fn1().fn2().fn3()</code>). Unless otherwise indicated in this documentation, a function is chainable in this manner unless a different return value is specified. This applies both to the core and to collections.</p><p>For functions that return a value, note that calling a singular — <code>ele</code>, <code>node</code>, or <code>edge</code> — function on a collection of more than one element will return the expected value for only the first element.</p><h2 id="notation/object-ownership">Object ownership <a href="#notation/object-ownership"><span class="fa fa-bookmark"></span></a></h2><p>When passing objects to Cytoscape.js for creating elements, animations, layouts, etc., the objects are considered owned by Cytoscape. Objects like elements have several levels to them, and doing deep copies of those objects every time they are passed to Cytoscape creates additional expense. When desired, the dev can copy objects manually before passing them to Cytoscape. However, copying is not necessary for most developers most of the time.</p><h2 id="notation/gestures">Gestures <a href="#notation/gestures"><span class="fa fa-bookmark"></span></a></h2><p>Cytoscape.js supports several gestures:</p><ul><li>Grab and drag background to pan : touch &amp; desktop</li><li>Pinch to zoom : touch &amp; desktop (with supported trackpad)</li><li>Mouse wheel to zoom : desktop</li><li>Two finger trackpad up or down to zoom : desktop</li><li>Tap to select : touch &amp; desktop</li><li>Tap background to unselect : desktop</li><li>Taphold background to unselect : desktop &amp; touch</li><li>Multiple selection via modifier key (shift, command, control, alt) + tap : desktop</li><li>Box selection : touch (three finger swipe) &amp; desktop (modifier key + mousedown then drag)</li><li>Grab and drag nodes : touch &amp; desktop</li></ul><p>All gesture actions can be controlled by the dev, toggling them on or off whenever needed.</p><h2 id="notation/position">Position <a href="#notation/position"><span class="fa fa-bookmark"></span></a></h2><p>A node’s position refers to the centre point of its body.</p><p>There is an important distinction to make for position: A position may be a <em>model</em> position or a <em>rendered</em> position.</p><p>A model position — as its name suggests — is the position stored in the model for an element. An element’s model position remains constant, despite changes to zoom and pan. Numeric style property values are specified in model co-ordinates, e.g. an node with width 20px will be 20 pixels wide at zoom 1.</p><p>A rendered position is an on-screen location relative to the viewport. For example, a rendered position of <code>{ x: 100, y: 100 }</code> specifies a point 100 pixels to the right and 100 pixels down from the top-left corner of the viewport. The model position and rendered position are the same at zoom 1 and pan (0, 0).</p><p>An element’s rendered position naturally changes as zoom and pan changes, because the element’s on-screen position in the viewport changes as zooming and panning are applied. Panning is always measured in rendered coordinates.</p><p>In this documentation, “position” refers to model position unless otherwise stated.</p><p>A node’s position can be set manually, or it can be set automatically using a <a href="#layouts">layout</a>. Because the positions of two nodes influence the lengths of the edges in between them, a layout effectively sets edge lengths.</p><h2 id="notation/elements-json">Elements JSON <a href="#notation/elements-json"><span class="fa fa-bookmark"></span></a></h2><p>Examples are given that outline format of the elements JSON used to load elements into Cytoscape.js:</p><pre><code class="lang-js">cytoscape({
