Dynamically Scale Node Sizes and Node Distances

[dtrammell]

As nodes have an increasing number of connections, the nodes around them can get quite crowded. I would propose having an option for the entire graph that would dynamically scale both the node sizes and distances to other connected nodes based on how many connections the node has. This way as the node gains more connections, it not only gets bigger, but "pushes" other nodes out farther away from it so that they have more room for their own connections.
