Mouse Follower

Mouse Follower

A circle follows the mouse cursor across an SVG canvas, centering itself on the pointer’s coordinates. The example demonstrates React state management to track mouse movement, updating the circle’s position on every move event. It uses React’s `useState` and `useCallback` hooks alongside D3 v6 for the SVG rendering, with an initial circle centered at 480, 250. The visualization responds interactively in real time, showcasing a minimal integration of React and D3 for dynamic graphics.

A circle follows the mouse cursor across an SVG canvas, updating its position in real time. The visualization is built with React and D3 v6, using React's `useState` and `useCallback` hooks to track and update the mouse coordinates from the `onMouseMove` event. The circle is rendered as an SVG element with a fixed radius, and its `cx` and `cy` attributes are bound to the current mouse position. The example demonstrates a simple interactive pattern in a React-D3 integration.

A circle follows the mouse cursor across an SVG canvas, with React managing its position in real time. The component uses React’s `useState` and `useCallback` hooks to track pointer coordinates from the `onMouseMove` event, updating the circle’s `cx` and `cy` attributes accordingly. The example demonstrates a minimal integration of D3.js (v5) with React, where D3 provides no visual functions—only the SVG rendering is handled by React, and the circle radius is fixed at 30 pixels. The canvas is 960 by 500 pixels, and the initial cursor position starts at the center.

A circle follows the mouse cursor across a full-screen SVG canvas. The circle's position is bound to the mouse coordinates, updated on every mouse move event. The example uses React with a `useState` hook to manage the cursor position, and the ReactDOM `render` method to mount the component. D3.js is loaded but not actively used in the rendering logic, which relies solely on native SVG elements and React event handling. The circle is drawn with a fixed radius of 30 pixels.

A circle follows the mouse cursor as it moves across an SVG canvas. The React component tracks pointer coordinates via the `onMouseMove` event and updates the circle’s `cx` and `cy` attributes through `useState` and `useCallback`. Rendered with D3 v5’s SVG helpers within React 16.9, the example demonstrates real-time state-driven positioning without external data.

Mouse Follower

A circle follows the mouse cursor within an SVG canvas, updating its position in real time as the pointer moves. Built with React, the application tracks mouse coordinates using an `onMouseMove` event handler and stores them in state via `useState`. The circle’s `cx` and `cy` attributes are bound to this state, and the SVG is rendered through ReactDOM. D3.js is included but not used for drawing; the interaction relies solely on React’s event system.

A circle follows the mouse cursor across an SVG canvas, creating a simple interactive visual response. The React application tracks cursor position through an `onMouseMove` event handler, updating state via the `useState` and `useCallback` hooks, and renders the circle using D3 v7 within an SVG element. The circle’s center coordinates are dynamically bound to the latest mouse position, with a fixed radius of 30 pixels.

A circle follows the mouse cursor across an SVG canvas, updating its position in real time. The example uses React's `useState` and `useCallback` hooks to manage mouse coordinates, with the `onMouseMove` event handler updating the circle's center. D3's `arc` module is imported but not used, while the SVG `<circle>` element is rendered directly through ReactDOM. The visualization demonstrates a simple interactive pattern without any data source or animation logic beyond direct mouse tracking.
