Mouse Follower

Mouse Follower

A yellow smiley face follows the mouse cursor across an SVG canvas. Built with React, the component tracks pointer coordinates through the `onMouseMove` event and updates a circle’s position via `useState` and `useCallback`. The SVG renders a single interactive shape with no predefined facial features, responding dynamically to user movement.

A smiley face rendered in SVG follows the cursor inside a 960×500 viewport. The React component tracks mouse movement via the `onMouseMove` handler and updates the circle’s position using state and the `useCallback` hook. The face is drawn with a yellow circle and two black eye circles, though the eyes remain static while the entire group moves. Rendering relies on React DOM with SVG elements, and the example highlights state-driven updates without external data sources.

A smiley face follows the mouse cursor across a full-screen SVG canvas. The application tracks the pointer's position and renders a yellow circle with facial features at that location, creating a playful interactive effect. Built with React and ReactDOM, the example uses the `onMouseMove` event handler and `useState` to update the circle's `cx` and `cy` coordinates dynamically. The SVG viewport matches the browser window dimensions, and the smiley face’s position updates instantly as the user moves the mouse.

A React and SVG-based smiley face follows the cursor across a 960-by-500 canvas. The application tracks pointer movement through the `onMouseMove` event, storing coordinates in state and positioning a single yellow circle accordingly. The rendering uses ReactDOM to update the SVG circle’s `cx` and `cy` attributes. The code relies on React’s `useState` and `useCallback` hooks for state management and event handling, with the visual output written in pure SVG markup.

A smiley face follows the mouse cursor across the full browser viewport, rendered as a yellow circle with black eyes and a stroke. Built with React and SVG, the component tracks pointer movement using React state and updates the circle’s position accordingly. The visualization uses React 16.9 and ReactDOM, with a hidden commented-out static SVG fallback showing the face’s initial geometry.

A yellow smiley face rendered as an SVG circle follows the mouse cursor across a full-screen viewport. Built with React, the component tracks pointer coordinates via the `onMouseMove` event and updates the circle's `cx` and `cy` attributes using the `useState` hook. The rendering relies on ReactDOM and SVG elements, with a production build of React 16.9.0. The visualization demonstrates a simple, reactive data binding between user input and graphical output, with no external data source.

A smiley face follows the mouse cursor across a full-screen SVG canvas. The React component tracks pointer coordinates via the `onMouseMove` event and stores them in state with the `useState` hook, updating the circle's `cx` and `cy` attributes through re-rendering. The `useCallback` hook memoizes the event handler, while rendering relies on React DOM and plain SVG elements with no external charting library.

A yellow smiley face follows the user's mouse cursor across a full-screen interactive SVG canvas. The face is drawn with React components that update its position based on mouse movement state. The example uses React 16.9's `useState` and `useCallback` hooks to track cursor coordinates and re-render the SVG circle elements accordingly. All rendering is client-side in the browser with no external data source.
