 # Features
 
 Beyond reading and writing GEXF files from within R, the **rgexf** R package has various other features that can help to create beautiful network visualizations, in particular:
-Using gexf objects--the main class implemented in rgexf--users can create GEXF objects from scratch, adding and removing nodes and edges--including features--as needed.
 
-Users of the **igraph** package can directly convert objects between `gexf` and `igraph` classes.
-Thanks to the **gexf-js** javascript library, users can immediately visualize their network objects in the web browser.

 Because of these and other reasons, the **rgexf** package has been featured in many scientific papers, stating the great utility that this R package has provided to the community. The **rgexf** package is available in the Comprehensive R Archive Network (CRAN) and the project repository at [https://github.com/gvegayon/rgexf](https://github.com/gvegayon/rgexf).
