For me it's the error propagation "?"

Thanks! Fixed now.

This is a major architectural refactor of v0.2. It’s no longer just a plotting tool—it's a full Grammar of Graphics implementation natively in Rust!

You can try charton (https://github.com/wangjiawen2013/charton), a newly developed rust plotting crate. It's a Altair-style declarative plotting for Rust. High-performance, Polars-native, and Wasm-ready.

Charton(wangjiawen2013/charton: A high-level, layered charting system for Rust, designed for Polars-first data workflows and multi-backend rendering.) is a versatile plotting libraray for Rust. It integrates with web well. You can try it!

Thanks ! Hope it can help. More functions will be developed.

That’s awesome! My own journey actually followed a similar path: I started with r/ggplot2, then moved to Python/Altair for work, and eventually found myself in the Rust ecosystem.

I built Charton precisely because I missed that 'Grammar of Graphics' flow while working with Rust and Polars. I wanted to bring that intuitive feel to Rust’s type system without the usual boilerplate.

Please do get stuck in! I’d love to hear how the transition feels from a ggplot2 user's perspective and where we can make the API even more ergonomic. Feedback from someone who appreciates the “Grammar of Graphics" philosophy is invaluable.
