Public service announcement - these kind of maps are known as isochrone maps and they're anything but new, but are (IMHO criminally) unpopular. They're extremely helpful when house hunting.

Agreed. It took weeks of researching to find this term when I was looking to optimize travel time search. Once I did, everything became easier! Ended up forking Open Transit Planner, this was back in 2015. Turned 40 minutes real estate searches into 40ms or so.
Wouldn't have helped you back then but LLMs are _spectacular_ at giving you the term that you don't really know what to google for.
Agree. I tried this with figuring out the name of a logical fallacy. And it led to a rabbit hole of info.
What is this Open Transit Planner and where do I find it?
I believe they're talking about http://www.opentripplanner.org/.
Is your fork available somewhere cause it sounds awesome!
They are to a point, I think.

I made one of these in the past when looking for places to live in London. The ultimate conclusion was that you could have inexpensive, short travel time, or nice/safe, choose two.

I gave up after realising that the market signals worked - if ignoring Central London it'd pretty much just be "more expensive = nicer"

They are also popular when establishing an office space, or when recruiting en masse for job opportunities/
Yeah I would have noticed that the place I’m renting for a month in Montreal is in dark shades of blue!
