//! # esoc-chart
//!
//! High-level charting API for data visualization, built on esoc-gfx.
//! Provides matplotlib-equivalent plotting for Rust ML workflows.
//!
//! ## New Grammar-of-Graphics API
//!
//! The new API provides 3 levels:
//! - **Express**: one-liner functions (`scatter`, `line`, `bar`)
//! - **Grammar**: composable `Chart`/`Layer`/`Encoding` types
//! - **Scene Graph**: direct access via `esoc-scene`
