This article shows how to build static and animated maps from GeoJSON, producing PNG, JPG, WebP, and animated GIF outputs — with full control over styles like colors, line widths, fonts, labels, and layout.

Instead of complex pipelines, the approach focuses on: - clear inputs (GeoJSON) - declarative styles (YAML) - deterministic image output The examples cover point maps and route rendering, fully functional and reproducible.
