Mapper-based visualization of functions

This software plots two BM graphs and color the one on the right according the the selected nodes on the left.

Please consult Mapping_Mappers.pdf for an introdution to the idea behind this code.
A short video example can be found at https://youtu.be/umSQt03kpPA .

requires networkx 2.5 and bokeh 2.2.2
https://networkx.org/
https://bokeh.org/

Usage:
$ bokeh serve --show two_graphs_viewer.py --args [GRAPH FILES]

Example
$ bokeh serve --show two_graphs_viewer.py --args knots_BM/alexander15/50_edges knots_BM/alexander15/50_points_covered_by_landmarks knots_BM/jones15/50_edges knots_BM/jones15/50_points_covered_by_landmarks

then visit http://localhost:5006/two_graphs_viewer on your browser (it should open automatically)

two_graphs_viewer.ipynb contains the same code, the local server is automatically launched inside jupyter.
