A single yellow circle follows the mouse cursor across an SVG canvas. The React component relies on an `onMouseMove` handler to capture pointer coordinates, which updates the circle's `cx` and `cy` properties. This example uses React 16.9 with hooks like `useState` and `useCallback`, and while D3 v5 is loaded, the visible rendering is plain SVG without any D3 functions. The initial mouse position is centered within the 960 by 500 viewport.

This example renders a single yellow circle that follows the mouse cursor across an SVG canvas. Built with React and D3 v5, it uses React’s `useState` and `useCallback` hooks to track pointer coordinates from the `onMouseMove` event, updating the circle’s `cx` and `cy` attributes in real time. The visualization demonstrates a minimal interactive pattern, combining React’s declarative state management with SVG’s native shape rendering.

A yellow smiley face follows the mouse cursor across an SVG canvas, with its circular head and facial features drawn in React and D3. The face tracks pointer movement via React state and an `onMouseMove` event, while D3’s `arc` function defines the smile shape. The implementation uses reusable SVG circle elements, fixed dimensions of 960 by 500 pixels, and a 20-pixel stroke for the head outline. The example demonstrates integrating React’s component state with D3’s geometry utilities for interactive visualization.

A single yellow circle follows the mouse cursor across an SVG canvas, responding to every pointer movement. Built with React 16.9 and ReactDOM, the application uses the `useState` and `useCallback` hooks to track the cursor's client coordinates and update the circle's `cx` and `cy` attributes in real time. The rendering approach is purely SVG, with a fixed viewport of 960 by 500 pixels. No external data source is involved; the visualization demonstrates interactive state management in a minimal React component.

A smiley face rendered as an SVG follows the mouse cursor across a 960×500 canvas. The example combines React for state management with D3.js for SVG generation, using a `circle` element whose `cx` and `cy` coordinates update via a `mouseMove` event handler. The React `useState` hook tracks the cursor position, and `useCallback` optimizes the event handler. Though the code defines a yellow face with black outline and two eye circles in an HTML comment, the interactive version displays only a single moving circle, driven by `ReactDOM.render` and D3 v5.

This example shows a yellow circle that follows the mouse cursor across an SVG canvas. Built with React, it uses the `useState` hook to track mouse coordinates and the `useCallback` hook to handle the `onMouseMove` event. The circle’s position is updated by setting the `cx` and `cy` attributes based on the pointer’s client coordinates. The visualization is rendered using React’s `ReactDOM.render` into a root element, with SVG as the output format.

This example shows a single yellow circle that follows the cursor across an SVG canvas, updating its position in real time based on mouse movement. Built with React and rendered as SVG, it uses the `useState` hook to track the mouse coordinates and the `useCallback` hook to handle `onMouseMove` events. The circle’s `cx` and `cy` attributes are bound to the current mouse position, and ReactDOM renders the component into a root element, with the canvas sized at 960 by 500 pixels.

A smiley face rendered as SVG responds to mouse movement, with a circle tracking the cursor across a screen-sized canvas. Eight yellow rectangles with black borders form the face’s background pattern, while the moving circle serves as a dynamic feature. The code combines React state management via `useState` and `useCallback` with D3 v5, using `Array.from` to generate the rectangles and inline SVG elements for rendering. React handles updates on `onMouseMove`, while D3 is imported but not directly used for drawing.

A single yellow circle follows the cursor across a full-window SVG canvas, its position driven by mouse movement events. The React component tracks pointer coordinates in state and re-renders the circle at the current location. The code uses React’s `useState` and `useCallback`, renders via `ReactDOM`, and updates an SVG circle element. The example demonstrates interactive mouse tracking in a React 16.9 environment.
