LineChart

Line Chart component for time-series and trend 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).

Source: packages/appkit-ui/src/react/charts/line/index.tsx
