PieChart

Pie Chart component for proportional data 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).
