The reason is mainly 1) licensing and 2) integration. I took what I found that fitted the BSD license and wrote the rest myself. The idea was having all the things I needed in a single, concise package. I like carrying around 1 MacGyver knife instead of a heavy toolbox - even if all the separate tools in the box are more robust than the knife. As for the JavaScript graph library: Daniel Friesen had already ported 90% of the Python code, so it only took me a day or two to finish it. The result is a single file (graph.js) with lots of things besides visualization (eigenvector centrality etc.) which seemed better suited to Pattern than integrating another, bigger project. Best, Tom
