Correlation Matrix
Compare signed association on a diverging scale with explicit missing relationships.
This is the installable component, not a mockup. Width is a preview container setting; theme and colors use your app’s shadcn CSS variables.

01 / Installation
Your code. Your project.
Use an initialized shadcn/Tailwind React project. The URL installs the component and its shared files recursively. No namespace configuration, platform account, or agent files.
Next.js, Vite & manual setup →npx shadcn@latest add https://beautifulcharts.dev/r/correlation-matrix.jsonPackage dependencies: echarts. Shared files are included in Source above. The installed license file covers the free source.
For a manual install, add those packages, copy every listed Source file to its displayed path, and adjust the @/ alias if your project uses a different one.
02 / Component API
Make it yours.
Types, defaults, and source below are generated from the distributed component. Numeric values must be finite; recipe-specific bounds are checked in source. Formatters change displayed labels, not the underlying measurements.

| title | string | "What moves together" | No |
