This React example demonstrates a bubble chart visualization using the `@weknow/react-bubble-chart-d3` library, which wraps D3’s force simulation for layout. The chart displays nine category labels—such as CRM, API, and Mobile—sized by numeric values, with a legend and custom click handlers for both bubbles and legend items. The rendering is encapsulated in an ErrorBoundary component that provides fallback error messages. The chart uses configurable graph properties for zoom and offset, while CSS handles label styling and hover behaviors for medium and small bubbles.
