Transforming a graph - a video

(just for fun)
I’ve been trying to finish a long project of creating swimlanes (see Swimlane - Wikipedia). Getting pretty close, but the program is even more convoluted and buggy than my norm. So I started making videos of the intermediate steps.
Can’t include video here, but here is a link Transforming a Graphviz graph to 3 swimlanes · GitHub
p.s. yes, still has bugs
