Modern chart rendering usually assumes a browser, a JavaScript runtime, or a frontend stack.
But many Ruby applications do not actually need interactive dashboards.
They need deterministic image generation.
Things like:
- scheduled reports
- PDF exports
- transactional emails
- admin dashboards
- analytics snapshots
- CI metrics
- server-side rendering pipelines
That was the motivation behind building RubyCharts: a lightweight chart rendering library written for backend-oriented Ruby workflows.
The project is still under active development, but the core idea is already working: generate PNG charts directly from Ruby using native rendering primitives.
The rendering backend is powered by ruby-libgd.
