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 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 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.

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 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.

This example shows a single gray circle centered in an SVG canvas, rendered using React and D3 v7. The circle is positioned statically at the midpoint of the 960×500 viewport, with no interactive data binding. It demonstrates React’s `ReactDOM.render` method to mount a functional component that returns an SVG `<circle>`, while a separate static SVG in the HTML displays two additional unfilled circles. A mouse move handler logs events to the console, but no visual feedback occurs. The rendering relies on React’s virtual DOM and D3’s SVG utilities.

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 I

A yellow circle with a black outline and a black arc smile follows the mouse cursor across an SVG canvas. Built with React and D3 v7, the smile is generated using the `arc()` generator from D3, while React's `useState` and `useCallback` hook react to `onMouseMove` events. The circle renders as an SVG element at the cursor's current position.

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.
