That’s a fascinating case study. Thanks for sharing. Not so long ago, I was designing visualisations for a different type of underlying graph structure, but one that had some similar elements in terms of “close” edges that could be drawn together, a desire to minimise edge crossings, and the like. I spent quite a while studying Beck’s famous London Underground map and its modern derivatives, and then experimenting with some of the same ideas mentioned in the article here. I too found that rendering clean, practical diagrams to show messy, real-world underlying data can be surprisingly difficult! I have a lot of respect for the Transit App team if they’ve successfully implemented algorithms that can produce output as beautiful as those examples in their general case.
