Fork of Smiley Face Part II

A fork of Smiley Face Part II shows a single unfilled circle following the mouse cursor across an SVG canvas. The circle's position updates in real-time based on the pointer's client coordinates. Implemented with React and D3 v7, the visualization uses React's `useState` and `useCallback` hooks to manage and update the mouse position state, while the SVG `<circle>` element renders the shape. The HTML loads React and D3 from CDN, and the code runs within a React component rendered to the root div.

This interactive React visualization displays a single black circle on a blank SVG canvas that follows the user’s mouse movements. It demonstrates a simple event-driven interaction where the circle’s center coordinates update in real time based on the pointer’s clientX and clientY values. Built with React 16.9, the app uses the useState and useCallback hooks to manage and update the mouse position state, while the SVG onMouseMove handler triggers these updates. The example shows how React’s declarative rendering can create responsive, mouse-tracked graphics in a minimal, frame-free environment.

This example shows a simple interactive visualization where a single circle follows the user's mouse movements across an SVG canvas. The React component tracks the mouse position using the `useState` and `useCallback` hooks, updating the circle's `cx` and `cy` attributes in real time. The code uses React 16.9.0 with `ReactDOM.render` to mount the SVG element, and the initial mouse position is set to the center of the 960×500 viewport.

A React app renders a single SVG circle that tracks the mouse position across the full viewport. The circle changes its coordinates based on the pointer's clientX and clientY values, using React's useState and useCallback hooks to manage and update that state. The visualization is built with React 16.9 and D3 v7, although the code does not utilize any D3-specific functions. The example demonstrates a basic interactive SVG rendering approach where the circle follows the cursor in real time, with no additional data sources or complex animations involved.

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.

This interactive visualization displays a single black circle that follows the user’s mouse movements across an SVG canvas. Built with React hooks (`useState`, `useCallback`) for state management and event handling, it renders via ReactDOM into a hidden-body layout. D3.js is included but not actively used in the code; the circle’s position updates directly from the `clientX` and `clientY` coordinates of mouse events. The example demonstrates seamless integration of React’s declarative rendering with browser mouse events for real-time SVG updates.

This interactive React visualization renders a single SVG circle that follows the mouse cursor across the full browser window. The circle’s position updates continuously based on the current mouse coordinates, using state management with React’s `useState` hook and event handling via `onMouseMove`. The app is structured with a full-window SVG canvas, and the circle’s radius is fixed at 30 pixels. The code imports React and ReactDOM, and the rendering is done through SVG elements, providing a minimal example of dynamic, mouse-driven graphics.

This example shows a single circle that follows the mouse cursor across an SVG canvas. The circle’s position is updated live based on pointer movement, with its center coordinates directly mapped from the browser’s clientX and clientY events. Built with React and D3 v5, the code uses React’s useState and useCallback hooks to manage the mouse position state, while rendering the circle as a SVG <circle> element. The interaction demonstrates a simple, responsive data-binding pattern between user input and a visual element.
