Color and thickness of connections

Change the thickness and color of connections for better graph perception.

Justification

More visible connections are much more noticeable when browsing the graph, and rich color (within reason) will emphasize them more. Also, if the thickness of the connections does not change depending on the scaling of the graph, this will also have a very good effect on reading the graph.

Implementation Details

It is desirable to make all further points configurable (for example, in the program settings).

  1. Make it possible to customize the colors of the connections to your taste, especially for connections between pins in shades of gray (at the moment they are very dim).
  2. Make it possible to customize the thickness of the connections.
  3. Make it possible to have a constant thickness of the connections regardless of the scaling of the graph.
