Making Maps with Ruby

Making Maps with Ruby

Static and animated cartography built directly from GeoJSON

For a long time, generating maps from code meant working inside heavy ecosystems designed primarily for analysis. Those tools are powerful, but they are not always the right fit. In many practical scenarios, the problem is simpler and more concrete: draw maps, show routes, place points, label them correctly, and have full control over how the final image looks.

Today, this kind of work can be done directly with Ruby.

Using libgd-gis , Ruby applications can generate static and animated maps from GeoJSON data, producing image outputs in PNG, JPG, WebP, and GIF , including animated GIFs for sequences and time-based visualizations. The focus is not on abstraction layers, but on building maps as visual artifacts: deterministic, reproducible, and fully controlled from code.
