## What it is
Idyll is a markup language and compiler toolchain for authoring interactive articles, explorable explanations, and data-driven stories on the web. It extends markdown with reactive variables and React components, and ships with a CLI for building, live-reloading, and publishing standalone pages or multipage blogs.

## Use cases
- write an explorable explanation with interactive charts
- publish a data journalism story with reactive variables
- create an interactive essay or tutorial that embeds D3 or Vega-Lite visuals
- build a multipage blog with interactive posts
- embed interactive components into an existing CMS or blog engine
- compile markdown-like markup into a standalone static webpage

## When to choose
- you want markdown-like authoring plus reactive variables and React components
- you need static output deployable to GitHub Pages or any static host
- you want built-in components for charts, inputs, and layout in articles

## When to avoid
- you need a general-purpose static site generator with heavy theming and plugin ecosystems
- you are building a traditional web application rather than article-style content
- you need a framework under active rapid development with frequent releases
- you want non-JavaScript authoring or non-React component ecosystems
