D3
This example demonstrates the VizHub V3 runtime environment, featuring an interactive SVG visualization. It displays a red circle that moves in response to mouse movement, with its position updated based on the cursor’s coordinates. The code uses React’s `useState` and event handlers, a constant `circleRadius`, and the container dimensions to render the circle’s movement. The SVG’s `onMouseMove` property triggers a state update, showcasing real-time interaction within the React framework.
