## ScatterChart[​](#scatterchart-1 "Direct link to ScatterChart")

Scatter Chart component for correlation and distribution visualization.

**Important:** This component uses Apache ECharts architecture. Configure it via props, not by passing child components.

**Best Practice:** Use the built-in data fetching by passing `queryKey` and `parameters` props instead of pre-fetching data with `useAnalyticsQuery`.

Supports both query mode (queryKey + parameters) and data mode (static data).
