Mouse Follower

A smiling cartoon face follows the mouse cursor across a yellow SVG canvas. The face is assembled from React components, with a yellow circle for a head, black-outlined eyes, and a curved mouth drawn using D3’s `arc` path generator. Mouse movement is tracked via an `onMouseMove` event listener, storing coordinates in React state and updating the rendered position of the face. D3 v6 provides the arc geometry, while React manages the interactive SVG rendering.

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 yellow smiley face rendered with React and SVG follows the mouse cursor across the screen. Built with React 16.9 and D3 v5, the face is constructed using SVG circles and a D3 `arc()` generator for the mouth. The program tracks pointer movement and updates the circle’s position accordingly, demonstrating simple mouse-event handling with SVG rendering in a React framework.

A smiling cartoon face follows the mouse across the screen, rendered as a yellow circle with eyes and an arc-shaped mouth. Built with React and D3 v7, the app tracks pointer movement via an SVG `onMouseMove` event, updating React state to reposition the face. The face’s components—background circle, eyes, and mouth—are composed from reusable React components, with the mouth drawn using a `d3.arc` path generator.

A yellow face with black-outlined eyes and an arched mouth follows the mouse cursor across an SVG canvas. The face is built from React components, including BackgroundCircle, Eyes, and Mouth, with d3.arc generating the mouth path. Mouse movement is tracked via React's useState and useCallback, updating the circle's center coordinates in response to clientX and clientY events.

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 cartoon face rendered in SVG follows the mouse cursor across the screen, with its yellow circular head repositioning to track pointer movement. Built with React and D3 v6, the face uses reusable components for the background circle, gradient-filled eyes, and an arc-based mouth. The `Face` component manages mouse position via React state and updates the circle's coordinates through `onMouseMove` events, while `range(1)` from D3 generates a single face instance.

A yellow smiley face follows the mouse cursor across an SVG canvas. The face’s components—eyes, brows, and an arc-shaped mouth—are built with React state and D3’s `arc` generator, repositioned via a `transform` attribute on each mouse move. The example uses `useState` and `useCallback` to track cursor coordinates, and ReactDOM renders the interactive graphic.
