Mouse Follower

Mouse Follower

A single circle follows the mouse cursor across a full-screen SVG canvas. Built with React and SVG, the example uses the `useState` and `useCallback` hooks to track `clientX` and `clientY` coordinates from the SVG element's `onMouseMove` event, updating the circle's `cx` and `cy` attributes in real time. The circle starts at the center of the viewport and moves smoothly with pointer input.

A circle follows the mouse cursor across a full-screen SVG canvas. The React component tracks pointer coordinates from the `onMouseMove` event and updates the circle's `cx` and `cy` attributes through `useState` and `useCallback`. The visualization uses React 16.9 with ReactDOM to render the SVG in production mode, positioning the circle at the exact client X and Y coordinates of the mouse.

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.

A circle follows the mouse cursor across an SVG canvas, updating its position in real time as the user moves the pointer. The React component uses the `useState` hook to store mouse coordinates and the `useCallback` hook with an `onMouseMove` event handler to update them. It renders a single `<circle>` element with the React DOM, ensuring smooth tracking without any external data source.

A circle follows the mouse cursor across an SVG canvas, updating its position in real time. The React component uses the `useState` and `useCallback` hooks to track mouse coordinates from `onMouseMove` events, then passes those coordinates to the circle's `cx` and `cy` attributes. The visualization is rendered with ReactDOM into a 960×500 SVG viewport.

A circle follows the mouse cursor across an SVG canvas as the user moves the pointer. The React component tracks the cursor’s `clientX` and `clientY` coordinates through an `onMouseMove` event handler, updating the circle’s `cx` and `cy` attributes via the `useState` and the component state. The visualization uses React 16.9 and ReactDOM to render the graph, with the SVG resized to 960 by 500 pixels and a constant circle radius of 30.

A circle follows the mouse cursor across an SVG canvas, updating its position in real time. Built with React using the `useState` and `useCallback` hooks, the component tracks mouse coordinates via an `onMouseMove` handler and renders the circle with `ReactDOM.render`. The SVG viewport is fixed at 960 by 500 pixels, with no data source or additional visual elements.
