Not exactly.

That link looks like a Ruby-level drawing demo (and I don’t see a public repo or docs behind it).

ruby-libgd is a native, in-process binding to libgd, focused on deterministic rendering and explicit pixel-level primitives, released under the MIT license.

On top of that, I built libgd-gis (also MIT) as a higher-level standard: map rendering, GeoJSON ingestion, layers, tiles, and reproducible output for GIS-style workloads.

ruby-libgd is the low-level graphics engine; libgd-gis is the map renderer built on it.

Yeah, its private stuff.. I added GRX Lib bindings to Ruby so I can use Ruby to do 2D graphics.. Ive been looking for somethink like this but couldnt find anything usefull for me, so I made one..

Here is example/demo: http://borg.uu3.net/~borg/?grx/test

gperf is not a demo, it my simple performance counters drawing app.

Thanks for the clarification — that makes sense. My goal with ruby-libgd / libgd-gis is to provide a public, documented, reusable graphics and map-rendering stack for Ruby.
