Fluvial - a transit patronage visualiser
My local public transit authority, TransLink, sporadically releases origin-destination patronage data.
I found myself wanting to visualise patronage flows for specific routes, and so I built Fluvial.
The tool generates what I am going to call "rainbow diagrams" - we have a line with stops running from left (start of the route) to right (end of the route). Arcs representing patronage flows swoop overhead. With appropriate colouration, the effect resembles a rainbow.

Note that this data is released only every few months; April 2019 is the most recent and before it, September 2018 was.
