## What it is
An experimental charting library for Svelte that creates responsive charts using CSS, requiring JavaScript only optionally. It was created by Rich Harris, the author of Svelte.

## Use cases
- add responsive charts to a Svelte app
- create charts that work without JavaScript
- build lightweight data visualizations
- make charts that resize fluidly with the page
- render simple bar and line charts declaratively

## When to choose
- you're building with Svelte and want idiomatic charting
- you need JavaScript-free responsive charts
- you want a lightweight alternative to heavy charting libraries

## When to avoid
- you need complex or highly interactive charts
- you're not using Svelte
- you need a mature, production-hardened library with long-term support

## Facets
- artifact type: library
- maturity: experimental
- function: data-visualization, charts, ui-components
- domain: data-visualization, frontend, web-development
- platform: -
- tags: svelte, responsive-charts, javascript-free, css-charts, web-server, nodejs
