For those interested in such things, here are 2 657 images showing the Office of Road and Rail 2021/22 passenger travel data projected onto a shortest-path network for each of the active mainline railway stations https://github.com/anisotropi4/kingfisher/blob/main/station.md
The main code still needs some work but the will be posted on GitHub here https://github.com/anisotropi4/kingfisher/
(There are already some helper scripts for generating markdown and creating the PNG images but not data yet)
