A single black circle follows the mouse cursor across a blank SVG canvas. The React component tracks pointer coordinates via the `onMouseMove` event, updating the circle’s `cx` and `cy` attributes with the client’s position. Using `useState` to hold the origin and `useCallback` for the handler, it re-renders the circle at the new location on every movement. The example demonstrates dynamic SVG updates driven by React state changes without external data.

Mouse Follower

A black circle follows the mouse cursor across a white SVG canvas. The React component tracks pointer movement via the `onMouseMove` event and updates the circle’s `cx` and `cy` attributes in response to `clientX` and `clientY` coordinates. It uses `useState` for mouse position and `useCallback` to handle event updates. The example demonstrates declarative SVG rendering with React and the ReactDOM `render` method, with a fixed canvas size of 960 by 500 pixels.

Mouse follower

A single black circle follows the mouse pointer across a blank SVG canvas. The React component tracks cursor coordinates through an `onMouseMove` event handler, storing them in state via `useState` and updating the circle’s `cx` and `cy` attributes. The app uses React 16.9 and renders the SVG directly with ReactDOM.

Mouse Follower

A single black circle follows the mouse cursor across an SVG canvas, with React tracking pointer events to update its position. The example uses React's `useState` and `useCallback` hooks to store the `clientX` and `clientY` coordinates on every `onMouseMove`, re-rendering the circle's `cx` and `cy` attributes. Rendered via ReactDOM into a 960×500 SVG, it demonstrates a minimal interactive data-visualization pattern without any external data source.

Mouse Follower

A single black circle follows the mouse cursor across a blank SVG canvas. The circle’s position updates in response to mouse movement via a React state hook (`useState`) and an `onMouseMove` event handler. The example uses React 16.9 for component rendering and event handling, with the SVG element created directly in JSX. No external data or D3 functions are used; only React’s state management drives the dynamic repositioning.

Mouse Follower

A circle follows the mouse cursor across an SVG canvas. The React component tracks pointer movement via the `onMouseMove` event handler, updating the circle’s `cx` and `cy` attributes in state. Rendering uses React’s `useState` and `useCallback` hooks, with the coordinate system based on the browser’s `clientX` and `clientY` values.

Mouse Follower

A React component tracks the mouse position and renders a single circle that follows the cursor across an SVG canvas. The application uses React’s `useState` and `useCallback` hooks to store and update the mouse coordinates, which are passed as `cx` and `cy` attributes to the SVG circle element. The circle starts centered on a 960 by 500 pixel viewport and moves smoothly in response to `onMouseMove` events. The example demonstrates a simple interactive pattern with React and SVG without any external data sources.

Mouse Follower

A single black circle follows the mouse cursor across an SVG canvas. The example demonstrates how React manages dynamic state alongside D3’s rendering environment. Using React’s `useState` and `useCallback` hooks, the component tracks mouse coordinates from the SVG’s `onMouseMove` event and updates the circle’s `cx` and `cy` attributes. The circle is rendered via React’s JSX, while D3 v5 is loaded but not directly used for interaction; the visualization relies entirely on React’s state updates to redraw the SVG element in real time.

Mouse Follower

A black circle follows the mouse cursor across a blank SVG canvas. The example demonstrates React state management with the `useState` and `useCallback` hooks, updating circle coordinates via the `onMouseMove` event. It renders a single `<circle>` element using ReactDOM, with a fixed radius of 30 pixels, and initializes the pointer position at the center of the 960×500 viewport.
