Ask HN: Is there a software to visualize and modify a graph?

In the past year there have been multiple times where I really needed a tool to visualize and modify a graph. Ex: visualize a complex build pipeline, visualize c++ include graphs, visualize inheritance graphs.<p>It would be great if the tool also enabled me to have some sort of way to see properties of each node&#x2F;edge in the graph.<p>Things I tried:<p>Python - networkx is great but the rendered graphs are not dynamic. Only static pictures.<p>Gephi - great for some analysis, but does not support layouting of the graph (for example a tree). Also seem to crap out of realtively small graphs.<p>Boost graph - Same issues as python networkx.<p>Visual Studio - really poor rendering performance. If you move a big graph it takes sometimes minutes for the graph to re-draw.
