That is awesome, thanks. I've been messing with it for hours but I have two questions...
1. When I try to create my own matrix, or constrain the weights in the random_matrix, the edge labels come back as 'none'. How do I create edge weights when I create the matrix? I need values b/w 0 and 1. I have tried a number of ways that I think should work but don't. Or, how do I use the DiGraph.weighted statement to put the matrix values as weights rather than number of edges connecting two vertices? 2. I need the slider to delete the exact vertex I want, not just drop off the last one - any idea on how to do that? (and it doesn't have to be a 'slider' it could be a selector or whatever it needs to be) Thanks again.
