Mouse Follower

Mouse Follower

A yellow circle follows the mouse cursor across a full-screen SVG canvas. The visualization is built with React hooks, using `useState` to track the cursor position and `useCallback` for the mouse-move event handler. The D3 library is available but not actively used; instead, React's rendering updates the circle’s `cx` and `cy` attributes in real time. The example demonstrates simple interactive state management within a React-D3 integration.

A yellow circle follows the cursor across an SVG canvas, updating its center position in real time as the mouse moves. The visualization uses React's state management with an `onMouseMove` event handler to track client coordinates, while D3.js provides the SVG rendering environment. The circle's position is bound to the mouse coordinates via React's `useState` and `useCallback`, creating a direct one-to-one mapping between input and visual output.

A yellow circle follows the mouse cursor as it moves across an SVG canvas. The visualization uses React state management with the `useState` and `useCallback` hooks to track the cursor's `clientX` and `clientY` coordinates, updating the circle's `cx` and `cy` attributes via React's render cycle. The SVG is rendered by ReactDOM, while D3 v5 is loaded but not directly used in this example. The circle maintains a fixed radius of 30 pixels and responds immediately to pointer movement within the 960×500 viewport.

A yellow circle follows the mouse cursor across a blank SVG canvas, tracking every movement in real time. The visualization demonstrates React state management, where mouse coordinates update the circle's position via the `useState` and `useCallback` hooks. Rendered as an SVG element, the circle's `cx` and `cy` attributes are bound to the current cursor position. The example uses React 16.9 and D3 v5, with the D3 `arc` function imported but unused, relying instead on React's event handling for interactivity.

A single yellow circle follows the mouse cursor across an SVG canvas. The example combines React state management with D3’s rendering capabilities, using the `useState` hook to track cursor coordinates and an SVG `onMouseMove` event handler to update them. The circle’s position is updated reactively on every mouse movement, demonstrating a simple interactive data binding between user input and a rendered visual element. The code imports React and ReactDOM directly, while D3 v5 is loaded via a CDN script tag for integration.

A yellow circle follows the mouse cursor within an SVG canvas as the pointer moves. The visualization uses React hooks and event handling, specifically the `useState` and `useCallback` functions, to track the cursor's `clientX` and `clientY` coordinates and update the circle's `cx` and `cy` attributes. The circle is drawn using React's SVG support, with the D3.js `arc` function imported but not used in the visible code. The canvas size is fixed at 960 by 500 pixels with a circle radius of 30.

A yellow circle with a black outline follows the mouse cursor across a blank SVG canvas, responding in real time to pointer movement. The visualization is built with React, using the `useState` hook to store the cursor's coordinates and an `onMouseMove` event handler to update them. D3.js is loaded for its utility functions, and the circle is rendered as an SVG element with ReactDOM, providing a simple demonstration of interactive state-driven rendering.

A yellow circle follows the mouse cursor inside an SVG canvas. The example demonstrates React state management with a `useState` hook to track the cursor's `clientX` and `clientY` coordinates, updating on every `onMouseMove` event. The app renders a single `<circle>` element with a radius of 30, initially centered at a fixed midpoint, and uses React's `useCallback` to optimize the handler. Built with React 16.9 and D3 v5, the rendering relies entirely on SVG output without external data sources.
