Chart.js

Canvas charts for dashboards, reports and embedded analytics.

Use it well

Register the controllers/scales you use or follow the auto entry guide. Give the canvas an accessible description or table; destroy instances on unmount. React wrappers are optional.

Install one suitable engine for the task. Existing shadcn charts remain useful for conventional React dashboards. Chart engines and integration recipes do not become complete application components just by installing their npm package.

Install

pnpm add chart.js

Check the consuming project's installed versions first; preserve its stack and theme. Renderer support is a library capability: alternate renderers or plugins can require additional dependencies. Provide real data, units, loading/empty/error states and an accessible table or explanation.

Verification and previews

Public package metadata and documentation links audited 2026-10-18. Initial package version: chart.js@4.5.1. The primary package declares no npm peer dependencies.

This is a metadata/reference audit, not a fresh-project runtime, browser, accessibility or performance verification. Generated entries retain current package metadata after sync. External examples stay on the source site; hosted adapters require separate implementation, attribution and browser checks.

Refresh this source with pnpm sync chartjs or the full group with pnpm sync charts, then pnpm catalog. Curated inputs live in catalog/chart-libraries.json; npm metadata is read without installing packages. Unknown or changed licensing fails sync for review.
