Creating graphic visualization in python

Question

Link shows a graphic visualization taken form census website. Link for the same is shared below. I want to create graphic visualization of the same kind in my python program.

Link for the graphic visualization: http://www.census.gov/dataviz/visualizations/stem/stem-html/

Which kind of visualization is this? is it a piechart or any other different kind of graphic visualization.

Are there any APIs available to create such a visualization or do i need to use any web service?

Answer 1

I don't see a graph that is exactly like the one listed, but matplotlib provides a huge number of options.

http://matplotlib.org/gallery.html

It supports Sankey graphs as well:

Answer 2

This tzpe of graph is called a chord diagram . a related question on stackoverflow can be found here . Bad news is there is no answer. And, unfortunately, looking around on the internet doesn't bring much.

Answer 3

As edouard mentioned, it is a Chord diagram. The D3js.org site has two examples - one static ( http://bl.ocks.org/mbostock/4062006 - which was listed in the other question edouard mentioned ) and one interactive ( http://bost.ocks.org/mike/uberdata/ ) which is more like the Census graphic.

Answer 4

It's essentially a weighted graph . It looks a lot like a Sankey diagram .

There is specialized software for visualizing graphs, eg graphviz . There are several Python bindings for it.

You would have to look at the documentation if it can create this style of graph.
