Equirectangular at a true two to one aspect, so the country outlines and the events share one projection. Country geometry is Natural Earth 1:110m, public domain. Note that the earthquake belts follow the plate boundaries, which are visibly not the coastlines.

The chart library

Every chart Readout can draw over these two catalogues. The map above is wired to the filters and the counters. These are not: each one answers its own question over the whole file, and each one opens into a detail view where the decisions it made are controls you can change. This is the set the case study draws its media from.
