MouseFollower

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.

A circle tracks the mouse cursor across a full-window SVG canvas, responding to every pointer movement in real time. React state updates the circle’s center coordinates on each `mousemove` event, using the `useState` hook and a `useCallback` handler. The visualization renders with React 16.9 and SVG, with no external data source or animation library—only direct event-driven position updates.

A React and SVG visualization renders a single black circle that follows the mouse cursor across a 960 by 500 pixel canvas. The circle’s position updates in response to mouse movement events handled through React’s `onMouseMove` callback, with state managed via the `useState` hook. The application uses ReactDOM to render the SVG element, and the circle’s center coordinates are dynamically set to the cursor’s client-space position, creating a direct and immediate tracking effect.

A circle follows the user's mouse cursor across a full-window SVG canvas, updating its position in real time. The visualization demonstrates React state management with the `useState` and `useCallback` hooks, where a `mousemove` event handler on the SVG element captures client coordinates. ReactDOM renders the circle at the stored mouse position, with the window dimensions defining the SVG's width and height. The code uses React 16.9 and renders purely with SVG elements, with no external data source.

A black circle follows the mouse cursor across a full-screen SVG canvas. The visualization uses React with the `useState` and `useCallback` hooks to track the cursor's `clientX` and `clientY` coordinates on every `mousemove` event. The current mouse position is stored in state and then passed as the circle's `cx` and `cy` attributes, causing the shape to render at the cursor's location at all times. The code relies on ReactDOM to mount the component, while the initial position is set to the center of the window.

Mouse Follower

A single black circle tracks the mouse in real time within an SVG canvas. The example uses React's `useState` and `useCallback` hooks to capture the mouse position via the SVG `onMouseMove` event, updating the circle's `cx` and `cy` attributes. The visualization demonstrates a minimal interactive pattern, relying on React for state management and D3 v5 only for SVG rendering support, with no data source beyond the live pointer coordinates.

A React SVG visualization renders a single black circle that tracks the mouse cursor across a 960 by 500 pixel canvas. The circle’s position updates via React state and the `useState` and `useCallback` hooks, responding to `onMouseMove` events on the SVG element. The code uses `ReactDOM.render` to mount the app and has no external data source, simply displaying interactive mouse-following behavior.

Mouse Follower

The visualization displays a single black circle that follows the mouse cursor across an SVG canvas that fills the entire viewport. React’s `useState` and `useCallback` hooks track the cursor’s client coordinates, which are updated via the SVG `onMouseMove` event handler. The circle’s `cx` and `cy` attributes are set to the current mouse position, and the component re-renders on every movement using `ReactDOM.render`. React 16.9 serves as the framework for this interactive, state-driven SVG rendering.
