## What it is
A Rollup plugin (also compatible with Vite and Rolldown) that visualizes JavaScript bundle composition through treemap, sunburst, flamegraph, and network charts. It helps developers see which modules take up the most space in their builds.

## Use cases
- analyze which npm dependencies bloat my bundle
- visualize vite bundle size per module
- find why a module is included in my rollup build
- generate a treemap of webpack-style bundle contents
- reduce javascript bundle size by spotting large modules
- inspect bundle composition in a sveltekit project

## When to choose
- you build with Rollup, Vite, Rolldown, or SvelteKit and want bundle size insights
- you need multiple chart types (treemap, sunburst, flamegraph, network) to explore bundle contents
- you want JSON stats reports you can merge via CLI

## When to avoid
- you use webpack or esbuild without a Rollup-compatible pipeline
- you need runtime performance profiling rather than bundle composition analysis
