Mouse Follower

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.

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, built from SVG circles and an arc, tracks the cursor across a full-screen canvas. The face renders with React components, including a d3.arc-generated mouth, while the center position updates via React state on mouse events. The app uses React's useCallback and useState hooks to manage the mouse coordinates, drawing the face inside a transparent SVG that spans the viewport.

A yellow smiley face with eyes and a mouth follows the mouse cursor across an SVG canvas. The React app tracks pointer movement via the `onMouseMove` event, updating the face's position through `useState` and `useCallback` hooks. The face is composed of reusable React components (`Face`, `Eyes`, `Eye`, `Mouth`), with the mouth drawn using a `d3.arc()` path generator. The rendering is entirely SVG-based, with a single `<circle>` for the face, two smaller circles for eyes, and a filled arc for the mouth, all positioned relative to the current mouse coordinates.

A yellow smiley face follows the user's mouse cursor across a full-screen interactive SVG canvas. The face is drawn with React components that update its position based on mouse movement state. The example uses React 16.9's `useState` and `useCallback` hooks to track cursor coordinates and re-render the SVG circle elements accordingly. All rendering is client-side in the browser with no external data source.

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 single yellow smiley face, rendered as an SVG circle with two smaller black circles for eyes, follows the mouse cursor across a 960×500 viewport. The React component tracks pointer movement via an `onMouseMove` handler and updates the face’s `cx` and `cy` attributes in state. D3’s `arc` utility is imported but unused; rendering relies entirely on React’s declarative SVG elements with no data source.

A yellow smiley face follows the mouse cursor across an SVG canvas. Built with React, the component tracks pointer coordinates through the `onMouseMove` event and updates a circle’s position via `useState` and `useCallback`. The SVG renders a single interactive shape with no predefined facial features, responding dynamically to user movement.
