I tried to build something similar to some of these samples using D3.js a while ago (modelling/visualising actual work being done, not statistically, at different stages between geting, assigning, starting, completing, returning, mainly to look for bottlenecks, but also to explain how our system worked). It was immediately obvious that D3 was not the best tool for the job, and I spent a fair amount of time looking for a framework that could do some of the more obvious stuff. Maybe I didn't know the right keywords to look for, but it seemed like it was a pretty empty space, so it's great to see more players in it. I really battled to figure out exactly what this was though. I think some code samples (if it is some kind of framework) or screenshots (if it is just an editor) would help a lot. Some of the overview links went to a "you need to be signed in to access this" page, and even when I tried to look at the examples, some were labeled "Python" but clicking on them didn't show me any Python code.
