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.

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 React and D3 interactive visualization displays a single circle that follows the mouse cursor across an SVG canvas. The code uses React's `useState` and `useCallback` hooks to track mouse coordinates, updating the circle's `cx` and `cy` attributes on every `mousemove` event. Rendered with React's `ReactDOM.render` into an SVG element, the example demonstrates how D3's SVG capabilities can be integrated with React state management for real-time user interaction.

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.

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 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.

Fork of Smiley Face Part II

A single yellow circle tracks the mouse across a full-window SVG canvas. The example demonstrates React state management with the `useState` and `useCallback` hooks, updating the circle's `cx` and `cy` coordinates on every `mousemove` event. Rendered with ReactDOM, it uses plain SVG circle elements without external visualization libraries. The code begins with an unused static smiley face layout, replaced by an interactive circle following the cursor.

A yellow circle follows the mouse cursor across an SVG canvas. The interface demonstrates basic pointer tracking using React state management, where `useState` stores the cursor’s `clientX` and `clientY` coordinates on each `mousemove` event. The `circle` element’s `cx` and `cy` attributes update dynamically from this state, while `circleRadius` remains fixed at 30 pixels. Rendered entirely with SVG within a React component, the example shows how declarative data binding enables smooth, responsive interactions without additional D3 utilities.
