A smiley face follows the mouse cursor across an SVG canvas, its position updating in real time with every pointer movement. The example combines React 16.9's `useState` and `useCallback` hooks to manage the circle's `cx` and `cy` attributes, while D3 v5 supplies the `arc` import. Rendering is handled through ReactDOM's `render` method, which places an interactive `<svg>` with an `onMouseMove` listener into the page root.

A smiley face circle follows the mouse cursor across a 960×500 SVG canvas. The visualization tracks pointer movement and repositions the circle's center to match the cursor's coordinates in real time. Implemented with React's `useState` and `onMouseMove` event handler, the circle's `cx` and `cy` attributes update from the mouse's `clientX` and `clientY` values. D3's `arc` function and React's `ReactDOM.render` manage the circle's geometry and rendering, while the SVG element provides the drawing surface.

Mouse Follower

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.

A smiley face rendered as a single SVG circle follows the mouse cursor across a 960×500 canvas. The React component tracks pointer coordinates via an `onMouseMove` handler and updates its position through `useState`, while D3’s `arc` utility is imported but unused. The circle’s `cx` and `cy` attributes are bound directly to the current mouse position, creating a smooth, direct mapping between input and visual output.

A smiling face follows the mouse cursor across an SVG canvas, responding instantly to pointer movement. The example demonstrates a minimal React integration with D3, using React's `useState` and `useCallback` hooks to track mouse coordinates and re-render the circle's position. Rendered as a single SVG circle, it relies on D3 v5's `arc` import, though the visible shape is a simple circle rather than an arc. The code pairs React 16.9 with d3.min.js, updating the circle's `cx` and `cy` attributes via React state on every mousemove event.

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.

A smiley face rendered as an SVG circle follows the mouse cursor across the browser viewport. The React application tracks pointer movement via an `onMouseMove` handler, updating the circle's `cx` and `cy` coordinates with the cursor's client position. The visualization uses React's `useState` and `useCallback` hooks to manage state, and D3.js is loaded for potential data manipulation, though the current implementation relies solely on SVG primitives within a React component.

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.

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.
