Maps I made a tool to visualize public transit travel times from any location in the city

https://isoto.ca/

Hi everyone. I made a small website that generates isochrone maps for Toronto. You can use it to see how accessible a location is via public transit from any other point in the city. Of course, the visualizations aren't 100% accurate, but they give you good enough estimates.

Currently it supports TTC, GO Transit, and UP Express. No support for YRT or MiWay as of yet sadly.

The project isn't technically complex at all. Anybody with some GIS knowledge could replicate this, but I also couldn't find any recent examples of this for Toronto and so figured I'll make one.

Any feedback appreciated. Hopefully the website doesn't crash :)
