Wow, I'm glad that I visited HN when your tool was at the top. I'm going to use it to illustrate docs on our internal DAG-like system. By the way, is there a simple way to export the animated diagram as a GIF?
I'm working on supporting webm first, as I am close to have a working feature using the MediaRecorder API of the browser. Exporting to gif will come after that, as it can be done by third-party tools as a workaround in the meantime (i.e. webm to gif).
