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.

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 interactive visualization displays a single circle that follows the mouse cursor as it moves across an SVG canvas. The circle’s position is updated continuously based on the user’s pointer coordinates. Built with React 16.9 and D3 v7, the app uses React’s `useState` and `useCallback` hooks to manage mouse-position state, while event handling is implemented via the SVG `onMouseMove` attribute. The visualization renders declaratively—when the mouse moves, the `cx` and `cy` attributes of the circle are recomputed, causing React to update the SVG in real time.

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 example shows a single circle that follows the user's mouse movement across an SVG canvas. Built with React 16.9 and rendered as SVG, the application uses the `useState` hook to track the mouse’s client coordinates and the `useCallback` hook to handle the `onMouseMove` event, updating the circle’s center position in real time. The visualization demonstrates interactive state management within a React component.

This interactive React application renders a single black circle that follows the mouse cursor across a 960 by 500 pixel SVG canvas. It uses the `useState` and `useCallback` hooks to track cursor coordinates from the `onMouseMove` event, updating the circle’s `cx` and `cy` attributes in real time. The visualization demonstrates a minimal, event-driven approach to direct manipulation within an SVG viewport.

This example shows a single unfilled circle that follows the mouse cursor across the full browser window, rendered as an SVG element. The circle’s center coordinates update continuously on mouse movement, using React’s `useState` and `useCallback` hooks to manage and optimize state changes. The visualization is built with React 16.9 and ReactDOM, rendering directly to the DOM, with the SVG’s `onMouseMove` event driving the interactive behavior. The underlying code includes commented-out static smiley-face circles, indicating the fork’s evolution from a fixed illustration to a mouse-tracking interactive graphic.

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.
