You can use rollup-plugin-visualizer;

import { visualizer } from "rollup-plugin-visualizer";
...
export default defineConfig({
  ...
  plugins: [
    ...
    visualizer({
      template: "treemap", // or sunburst
      open: true,
      gzipSize: true,
      brotliSize: true,
      filename: "analyse.html", // will be saved in project's root
    }) as PluginOption,
    ...
  ],
  ...
});

Alternatively, you can use vite-bundle-visualizer, which uses rollup-plugin-visualizer:

npx vite-bundle-visualizer

Usage

# In your vite project's root
$ npx vite-bundle-visualizer
# Then open stats.html in browser

$ npx vite-bundle-visualizer --help

vite-bundle-visualizer

Usage:
  $ vite-bundle-visualizer <command> [options]

Options:
  --template -t <template>  Template to use, options are "raw-data" (JSON), "treemap", "list" (YAML), "sunburst" and "network" (default: treemap)
  --output -o <filepath>    Output file path, should be "**/*.html" or "**/*.json" (default: /Users/kuss/project/sides/oss/vite-bundle-visualizer/stats.html)
  --open <open>             Should open browser after generated, except when template is "json" (default: true)
  -h, --help                Display this message
