Not sure if there is any utility in this, but I created a (not really) time-lapse video of **dot** working on a graph.  
OK, not really a _time-lapse_ - really 12 individual **dot** runs with varying values for **nslimit** (01 04 16 32) ([nslimit | Graphviz](https://graphviz.org/docs/attrs/nslimit/)) and **mclimit** ( 0.1 0.5 1.0) ([mclimit | Graphviz](https://graphviz.org/docs/attrs/mclimit/)) to throttle the work done by the major internal routines.

the home movie: [subway.mp4 - Google Drive](https://drive.google.com/file/d/1fGnLPJPCByXPO3ID-Ja9yLPN_JB5cJ1c/view?usp=sharing)

I was surprise at how much things changed from one image to the next. **Dot** is a hard worker.  
Nothing special about this graph, other than colored nodes & edges. I did not create it.

Don’t forget your popcorn!
