Tufte Slopegraphs

A Python, SVG take on this Edward Tufte challenge

slopegraph.py will generate a D3.js document and a LaTeX file containing slope graphs of input data, with a specified title.

svg.py

svg.py contains code that generates the SVG image test.svg. This implements a two-column slopegraph, to be embedded in a document with a title, etc.

slopegraph.py

User specifies two items in slopegraph.py: filename and title.

filename specifies a source data file, which is comma separated with three columns:

1. label: Item label
2. col1: Column 1, titled "col1" (or whatever)
3. col2: Column 2, title "col2"

title, appropriately, gives the title of the chart.
