Plotters is a Rust drawing library for rendering figures, plots, and charts in pure Rust with support for both WebAssembly and native applications.
The library solves the problem of creating high-quality data visualizations across different platforms and rendering contexts. It achieves this through a modular backend architecture that abstracts the drawing surface, allowing the same plotting code to target bitmap outputs, vector graphics, GTK/Cairo windows, Piston windows, and WebAssembly environments. This design means developers write visualization logic once and deploy it across multiple platforms without rewriting core plotting code.
Plotters suits projects where you need to generate plots programmatically in Rust without heavy dependencies or where you want to embed interactive visualizations in web applications via WebAssembly. It works well for scientific computing, data analysis tools, and real-time monitoring applications. The library is particularly valuable if you need to avoid JavaScript charting libraries or if your plotting logic naturally fits within a Rust application. The project has moved some backend implementations to separate repositories, so you should check which backends are maintained as separate crates depending on your target platform.
The project maintains active development with regular updates to core functionality and backend support. Documentation is being actively expanded with a developer's guide in progress. The maintainers provide interactive examples through Jupyter notebook integration and a live WebAssembly demo, indicating ongoing effort to make the library accessible to new users. The modular backend architecture continues to evolve, with backends being extracted into separate repositories as the ecosystem matures.
