It has a live map of public transport around the world, mostly showing the actual vehicle positions (although we interpolate from the estimated arrivals for some European operators). You can also click on vehicles (trains, buses, ferries, etc) to see their past and predicted future arrivals, click on a station to see its departure board, or click on a line to see its variants.
I tried out the multivariable calculus visualizations from https://nmd.web.illinois.edu/classes/2024/241/schedule.html (search for "visualization") and Woxi Studio seems to be able to display them. I'm not sure if it's entirely correct (there might be a few bugs) since I don't have Mathematica currently to serve as a comparison.
