## What it is
Charming is a Rust chart rendering library built on Apache ECharts, offering a declarative API for creating rich, themed visualizations. It renders to HTML, SVG, and many raster formats, and works in WebAssembly environments.

## Use cases
- render charts from rust
- generate svg charts in a rust backend
- visualize data in wasm apps
- create png chart images server-side
- build dashboards with echarts from rust

## When to choose
- you want ECharts-quality charts from Rust code
- you need a declarative chart API with many themes and output formats
- you're building WebAssembly frontends in Rust

## When to avoid
- you need interactive charts in a pure non-web Rust environment
- you prefer a native Rust plotting engine like plotters
- you need Python-style notebook plotting workflows

## Facets
- artifact type: library
- maturity: active
- function: data-visualization, charts
- domain: data-visualization, data-science, web-development
- platform: rust, wasm, cross-platform
- tags: echarts, chart-rendering, declarative-api, svg, png
