A smiley face drawn with SVG circles follows the mouse cursor across the full browser window. The example uses React’s `useState` and `useCallback` hooks to track mouse position on the `<svg>` element, updating the circle’s `cx` and `cy` attributes in response to `onMouseMove` events. Rendering is handled by ReactDOM, with the viewport dimensions determined by `window.innerWidth` and `window.innerHeight`. The code includes a static yellow smiley face in a commented block, but the active visualization shows only a single black circle.

mouse follower

A smiley face rendered as an SVG circle tracks the cursor's movement across a full-window canvas. The code uses React hooks, specifically `useState` for mouse coordinates and `useCallback` for the event handler, to update the circle's `cx` and `cy` attributes on every `mousemove`. The visualization displays a single yellow circle with black outlines, omitting facial features, and directly lands on the `clientX` and `clientY` properties of the mouse event.

Mouse Follower

This example shows a smiley face that follows the mouse cursor across the full browser window. The face is rendered as a single yellow circle with two smaller black circles for eyes, drawn using React state and inline SVG. The code uses React's `useState` hook to track the mouse position via `onMouseMove`, updating the circle's `cx` and `cy` attributes in real time. It renders using React DOM into an SVG element sized to the viewport dimensions.

Mouse Follower

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.

Mouse Follower

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.

Mouse Follower

A smiley face drawn in SVG follows the cursor as it moves across the viewport. React manages the circle’s position via the `useState` and `useCallback` hooks, updating `cx` and `cy` attributes on every `onMouseMove` event. The example uses React 16.9 and renders directly into a full-screen SVG element without any data source.

Mouse follower

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.

Mouse Follower

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.

Mouse follower

A cursor-following smiley face tracks the mouse across an SVG canvas in this React application. The code uses React's `useState` hook to store mouse coordinates and a `useCallback` handler to update them on `onMouseMove` events. Each mouse movement re-renders a single yellow circle with black stroke, whose center position is bound to the current mouse coordinates. The example demonstrates real-time interaction between browser pointer events and declarative SVG rendering through React's state management.
