This example shows an interactive smiley face rendered as a circle that follows the mouse pointer across an SVG canvas. The circle’s center coordinates update in real-time based on the pointer’s position within the viewport. Built with React and D3 v7, the app uses React state and the `onMouseMove` event handler to track the pointer, while the SVG `<circle>` element is updated via React’s declarative rendering. The mouse position is captured from `clientX` and `clientY` properties, with the initial position set to the canvas center.

mouse follower

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 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 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 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

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.

Mouse Follower

A reactive SVG smiley face follows the pointer across the browser viewport, using React state and event handling to update its position. The code defines a single circle element that tracks the mouse's client coordinates within an SVG canvas sized to the window dimensions. React’s `useState` and `useCallback` manage the updated position, while `ReactDOM.render` mounts the component. The example demonstrates basic interactive SVG visualization with React, where the graphic responds directly to user input.

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 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.
