Mouse Follower

Mouse Follower

A smiley face rendered in SVG follows the mouse cursor across a yellow background. The face, built from React components for the background circle, eyes, and a d3.arc-generated mouth, updates its position via React state on every mousemove event. The visualization uses React’s useCallback and useState hooks to track client coordinates, re-rendering the face container at the new location.

A smiling face drawn with React SVG components follows the mouse cursor across the screen. The face is composed of reusable React components (BackgroundCircle, Eyes, Mouth) that use d3.arc for the mouth path. The app tracks mouse movement via React’s onMouseMove and useState hook, updating the circle’s cx and cy coordinates in real time. The visualization demonstrates interactive, state-driven rendering with React 17 and d3.v7, tightly coupling user input to SVG output.

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.

A smiling face rendered in SVG follows the mouse across the screen. Built with React and D3 v5, the example uses D3’s `arc` generator to create the mouth, while the face circles, eyes, and stroke are defined as React components. The entire SVG group is translated to the viewport center, and the mouse follower behavior is implied by the full-screen, overflow-hidden layout, though no explicit mouse event handlers appear in the code. The static smiley face adapts to its container dimensions.

Mouse Follower

A smiling face rendered as an SVG using React and D3 follows the mouse cursor across the screen. The face is constructed with D3’s `arc()` generator for the mouth, alongside static circle elements for the eyes and face outline. The component uses React’s declarative JSX to define the SVG structure, while D3 v5 calculates the path geometry. Mouse movement triggers a transform on the root group, shifting the entire face to track the cursor’s position. The example demonstrates hybrid React-D3 integration for interactive visualization.

Mouse Follower

A smiley face drawn with SVG follows the mouse cursor in real time. The face is built from circles for the head, eyes, and mouth, and it tracks the pointer’s position across the full browser window. Using React’s `useState` hook and an `onMouseMove` event handler on the SVG element, the component updates its center coordinates on every cursor movement. The code relies on the React and ReactDOM libraries, rendering the dynamic graphic via JavaScript’s `window.innerWidth` and `window.innerHeight` to adapt to screen size.

This example shows a simple smiley face that follows the mouse cursor across a 960-by-500 SVG canvas. The face is drawn with a yellow linear gradient, two elliptical eyes, and a d3.arc-generated mouth, all assembled from React components. As the user moves the mouse, the React state updates the circle’s center coordinates via the `onMouseMove` handler, re-rendering the face at the new position. The code uses React’s `useState` and `useCallback` hooks, along with d3’s `arc` for the mouth path, and renders everything as SVG elements.

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.
