This example demonstrates a circle following the mouse cursor inside an SVG canvas using React’s `useState` hook to track position changes. The visualization updates the circle’s `cx` and `cy` attributes in response to the `onMouseMove` event, rendering with ReactDOM and D3.js v5 as a dependency. The code relies on clientX and clientY coordinates from the event object to reposition the circle dynamically, with the initial state centered at half the SVG’s width and height.

This example demonstrates a mouse follower visualization where a circle tracks the cursor’s position across an SVG canvas. The React app uses the `useState` hook to store mouse coordinates, updating them on every `onMouseMove` event. The circle radius is fixed at 50, and it renders via ReactDOM into an HTML root element. The visualization highlights real-time interaction, with the SVG’s width and height set to 960 by 500 pixels. It relies on React 18.2.0 and ReactDOM for rendering, showing how state management and event handling create a responsive graphical effect.

A circle follows the mouse cursor across an SVG canvas, responding to every movement with a smooth, immediate position update. Built with React and D3 v6, the example uses React's `useState` hook to track mouse coordinates and passes them as `cx` and `cy` attributes to a single SVG `<circle>` element. The `onMouseMove` event handler updates the state on each pointer movement, while the viewport is fixed to 960 by 500 pixels with no overflow. This demonstrates a minimal interactive pattern combining React's declarative state management with SVG rendering.

A circle follows the mouse cursor across an SVG canvas, its position updating in real time as the pointer moves. Built with React 18, the app uses `useState` to track the cursor's `clientX` and `clientY` coordinates, which are bound to the circle's `cx` and `cy` attributes. An `onMouseMove` handler on the SVG element triggers the state update, while ReactDOM renders the component into the DOM.

This example demonstrates a minimal interactive mouse-follower where a single circle remains stationary at the center of an SVG canvas. The visualization uses React to render an `<svg>` element with a fixed radius circle, while CSS hides any page overflow. The code leverages React’s component model and JSX syntax, with dimensions hardcoded as constants. Although a script tag references an external library, no mouse-tracking behavior is implemented in the visible code, making it a static starter template for further development.

A React component renders an SVG circle that follows the mouse cursor across a 960x500 viewport. The application uses React's `useState` hook to track the cursor's `clientX` and `clientY` coordinates, updated by an `onMouseMove` event handler on the SVG element. The circle's `cx` and `cy` attributes bind to the stored position, creating a direct visual response to pointer movement. The visualization demonstrates a simple, interactive SVG rendering approach using React 18 and ReactDOM.

This example shows a single circle following the mouse as it moves across an SVG canvas. The circle’s position updates continuously based on the cursor’s client coordinates, shifting smoothly across a 960×500 viewport. The visualization uses React’s `useState` and `useCallback` hooks to manage and update the mouse position, while `ReactDOM.render` mounts the component into the DOM. The SVG `<circle>` element is rendered directly, with its `cx` and `cy` attributes bound to the current mouse coordinates.
