# Fluvial — a transit patronage visualiser
Date: 2020-12-13

My local public transit authority, TransLink, releases
[origin-destination patronage
data.](https://www.data.qld.gov.au/dataset/go-card-transaction-data)

I found myself wanting to visualise patronage flows for specific routes,
and so I built [Fluvial.](https://github.com/alexjago/fluvial)

The tool generates “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:

You even can mouse over the arcs in the SVGs for a more detailed
description of the patronage flow.

## Browse the output

There are index pages linked below for each month, which in turn links
to an SVG file for each route and direction. You may need to adjust the
zoom level, or scroll around, especially for routes with many stops.
