How to make a circular tilemap

Hi, I am trying to make a circular tilemap (see image below).


I’ve gotten as far as creating the points in the grid using gizmos (see below).

Is there a way this can be done?

Well, I’d say you need to generate some procedural geometry/mesh from your data. Can this be done? Very sure yes. Is there a trivial answer like a line of code that will save you? Probably not.
All that Unity provides that you can use is the Mesh class and some Math tools included in the framework.
