Geometry Guide

51 exotic geometries — 226 data sources — 257 metrics

Each geometry is a question asked of data. The answers are gradients from low to high, with specific atlas sources as landmarks. These pages explain what each geometry detects through contrast and atlas examples, not mathematical definitions.
