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?

elow are the steps to learn visualization from basic,

• Step 1: Importing data
• Step 2: Basic visualization using Matplotlib
• Step 3: More advanced visualizations, still using Matplotlib
• Step 4: Building quick visualizations for data analysis using Seaborn
• Step 5: Building interactive charts

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:

http://matplotlib.org/api/sankey_api.html?highlight=sankey#module-matplotlib.sankey

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

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

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