OpenGL State Snapshot JSON File - Visualized as a Graph

Been using graphviz's dot tool to visualize JSON files containing OpenGL state snapshots. This tree only contains high-level GL state. The large texture, buffer, shader, etc. data is written to loose binary files and referenced by unique filenames in the JSON data, which isn't represented here.

I had to limit the max # of values per JSON array/object to 20 otherwise dot falls over and takes hours to complete. I wish I knew of a faster graph visualization tool.
