A black circle follows the mouse pointer across an SVG canvas in a React application. The example demonstrates interactive state management by tracking the cursor's coordinates through React's `useState` and `useCallback` hooks, updating the circle's `cx` and `cy` attributes on every `mousemove` event. It uses React 17 with the `ReactDOM.render` API, while D3.js v6 is loaded but not directly utilized in the visible logic.

Smiley Face Part III

This example uses React and D3 v7 to render a single SVG circle that follows the mouse cursor. The circle’s center coordinates are updated via React state on every mouse move event, using the `onMouseMove` handler. The code leverages D3’s `arc` module and React’s `useState` hook, with a fixed canvas size of 960 by 500 pixels. The result is an interactive smiley face that tracks pointer movement in real time.

Smiley Face Part 2

A smiley face remains static and centered, while a single gray circle tracks the mouse movement across the SVG canvas. The React component uses `useState` and `useCallback` to update the circle's `cx` and `cy` attributes on every `mousemove` event, rendering via ReactDOM. The example demonstrates interactive SVG rendering with React and D3 v7, though it does not use D3-specific APIs beyond the imported library.

A single black circle follows the mouse cursor across a blank SVG canvas, responding to every movement with a one-to-one positional update. The React component tracks the pointer via the `onMouseMove` event and stores the coordinates in state using the `useState` hook, while `useCallback` optimizes the handler. ReactDOM renders the scene, and the circle's center is set directly to the cursor's clientX and clientY values, creating a simple, immediate interactive visualization.

Smiley Face Part 1

A single gray circle follows the mouse cursor across an SVG canvas, its position updating live as the pointer moves. The visualization demonstrates React state management with the `useState` and `useCallback` hooks, where mouse coordinates from the `onMouseMove` event drive the circle’s `cx` and `cy` attributes. Rendered via ReactDOM into a root div, the SVG uses D3 v6 for its helper functions, with a fixed 960×500 viewport and a 30-pixel radius. No external data is loaded; the interaction is purely event-driven.

Smiley Face Part II

A lone black circle follows the cursor across a blank, full-window SVG canvas. Built with React, the app tracks the pointer's coordinates through the `onMouseMove` event, stores them in state with `useState`, and re-renders a single `<circle>` element at the current position. The example uses React 16.9 and ReactDOM to update the SVG in real time, demonstrating a minimal interactive visualization driven by mouse input.

Fork of Smiley Face Part III

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.

Smiley Face Part II

A yellow circle follows the mouse cursor across a 960 by 500 SVG canvas. The example demonstrates stateful interaction in React, where the circle's center coordinates update based on the cursor's position. The React app uses the `useState` hook to track mouse movement and ReactDOM to render the SVG element, which handles the `onMouseMove` event.

Smiley face Part 1

A yellow circle follows the mouse cursor across an SVG canvas, responding to pointer movement. The visualization uses React's `useState` hook and `onMouseMove` event to track the cursor position, updating the circle's `cx` and `cy` attributes with the current coordinates. The D3.js library and React bindings render the SVG element, with the D3 `arc` function imported but unused. The graphic demonstrates real-time coordinate mapping through React state management.
