It&#x27;s not entirely you, but I think that the fundamental problem is less with the visualization than with shortcomings of the implementation.  With regards to the implementation, I have trouble reading the unselected text.  With regards to the visualization itself, the switchboard-style network view is really neat, and the line coloration idea was clever, but thickness of lines is really hard to infer proportional information from.  There really needs to be supplementary information appearing dynamically alongside the grid.
