Hierarchical Edge Bundling
Hierarchical edge bundling allows to visualize adjacency relations between entities organized in a hierarchy. The idea is to bundle the adjacency edges together to decrease the clutter usually observed in complex networks.
Hierarchical Edge Bundling with R or Javascript
Contrary to python that is not of much help to build a hierarchical edge bundling, R and Javascript both offer built-in functions to make them. R will be more adapted if you're a data analyst and are happy with a static version. Javascript and thed3.js library offers more customization and interactivity options, but comes with a steeper learning curve and a lot of line of code. Pick your flavor!
