Chord diagrams allow to visualize flows between several entities. Each entity is represented by a fragment on the outside of the circle. Then, arcs are drawn between each entities. The size of the arc is proportional to
the importance of the flow. Unfortunately, there is currently no specific library allowing to make proper chord diagram in python. It is possible to make it using plotly, but it takes a lot effort. Bokeh is another option,
but the result is not entirely satisfying. It is hard not to propose you to use R and the awesome circlize package! If you have any other example that could be helpful to this section, I would be delighted to add it!
