npm add libchartium unitlib fraction.js

pnpm add libchartium unitlib fraction.js

bun add libchartium unitlib fraction.jsYou will also need to make sure that your bundler can import WebAssembly as ES modules according to the ESM integration proposal. For Vite that means you need to add vite-plugin-wasm, for Rollup it's @rollup/plugin-wasm. In Webpack you'll have to allow asyncWebAssembly in the config.
