A smiley face follows the mouse cursor across an SVG canvas, with its position updating in real time. The visualization uses React state and the `useState` and `useCallback` hooks to track mouse coordinates, which are passed to an SVG `<circle>` element’s `cx` and `cy` attributes. The `onMouseMove` event handler on the `<svg>` element triggers the state update, while ReactDOM renders the component. No D3 APIs are used; the example relies purely on React’s declarative rendering with SVG.

Mouse Follower

A smiling face follows the mouse cursor across an SVG canvas, updating its position in real time as the pointer moves. The visualization uses React 16.9 with the `useState` and `useCallback` hooks to track mouse coordinates via the SVG `onMouseMove` event. A single circle is rendered at the current cursor position, with its `cx` and `cy` attributes bound to the state. The rendering is done entirely through React's declarative JSX, with no external data source or animation library.

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.

Mouse Follower

A React-based smiley face follows the mouse cursor across an SVG canvas. The example demonstrates interactive state management with React's `useState` and `useCallback` hooks, responding to `onMouseMove` events to update circle coordinates. The rendering uses SVG elements composed with ReactDOM, creating a minimal interactive visualization where a single circle tracks pointer movement within a 960x500 viewport.

Mouse Follower

A smiley face follows the mouse cursor across the screen, rendered as a single SVG circle that moves in real time. The React component tracks pointer coordinates via the `onMouseMove` event handler, updating state with `useState` and `useCallback` to reposition the circle’s center. The visualization uses React DOM to render the SVG element directly to the page, with the circle’s radius fixed at 30 pixels. No external data sources are involved; the interaction is purely based on mouse position.

Mouse Follower

A smiley face visualization renders a circle that follows the mouse cursor across an SVG canvas. Using React's `useState` and `useCallback` hooks, the application tracks `clientX` and `clientY` coordinates from the `onMouseMove` event, updating the circle's `cx` and `cy` attributes in real time. The visualization is built with ReactDOM, which renders the SVG element directly into the HTML document, providing immediate interactive feedback as the user moves the pointer.

Mouse Follower

A smiley face follows the mouse cursor on an SVG canvas, with a yellow circle acting as the face and a smaller circle representing its mouth. Built with React and ReactDOM, the component tracks the cursor’s position via the `onMouseMove` event and updates state with the `useState` and `useCallback` hooks, re-rendering the SVG circle’s `cx` and `cy` coordinates accordingly.

A smiley face rendered as an SVG circle follows the mouse cursor across the full window. React state tracks the pointer position via an `onMouseMove` handler, and the circle’s `cx` and `cy` attributes update accordingly. The implementation uses React 16.9 with hooks (`useState`, `useCallback`) and renders directly to SVG, with the viewport size set from `window.innerWidth` and `window.innerHeight`.

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.
