A smiley face drawn with SVG circles follows the cursor inside a 960 by 500 canvas. The React component tracks mouse movements via an `onMouseMove` handler, updating state to reposition a single circle. While the static markup comments include a complete face, the active code renders only the follower circle using React's `useState` and `useCallback`. The example demonstrates combining React's declarative updates with D3's SVG scene graph for interactive visualizations.

Mouse follower

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.

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 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.

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.

Mouse Follower

A smiling face emoji, rendered as a single SVG circle, follows the mouse cursor across a 960 by 500 pixel canvas. The React component uses the `useState` hook to track the mouse position, which is updated on every `onMouseMove` event on the SVG element. React 16.9 handles the state-driven re-rendering, while D3 v5 is loaded but not directly used in this example. The circle’s center coordinates are bound to the current mouse position within the SVG coordinate system.

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 smiling cartoon face renders in SVG using React components for the background circle, eyes, and mouth, all positioned within a transformed group. As the mouse moves over the svg element, a separate filled circle follows the cursor’s client coordinates. The face itself integrates D3’s `arc()` generator for the mouth shape and static eye offsets, while React’s `useState` and `onMouseMove` handler update the follower circle’s position.

Mouse Follower

This is a React application that renders a single smiley face as an SVG circle, which follows the mouse cursor across the screen. The component tracks pointer movement through React's `useState` and `useCallback` hooks, updating the circle's center coordinates with each mouse event. The SVG is rendered with React, while the page loads React and D3 v5 from CDN links in the HTML. The interactive behavior is driven entirely by React's event handling, not by D3's own mouse utilities.
