Mouse Follower

Mouse Follower

A React and SVG visualization that tracks the mouse cursor with a single circle. The circle's position updates live as the user moves over a 960 by 500 SVG canvas, using React's `useState` and `useCallback` hooks to manage the cursor coordinates and an `onMouseMove` event handler. The circle is rendered as an SVG `<circle>` element with a fixed radius of 30 pixels, while the initial position is centered on the screen.

A React application renders an SVG circle that follows the mouse cursor across a 960-by-500 viewport. The component tracks pointer coordinates via the `onMouseMove` event handler, updating React state with the client X and Y positions, which are then bound to the circle's `cx` and `cy` attributes. The visualization demonstrates real-time state-driven SVG manipulation using React hooks (`useState`, `useCallback`) and ReactDOM, with no external data source or animation library.

A React application renders an SVG circle that follows the mouse cursor across a 960 by 500 pixel canvas. The circle's position updates in real-time via React state and the `onMouseMove` event handler, reading the cursor's `clientX` and `clientY` coordinates. When the mouse leaves the SVG area, the circle returns to its initial centered position through the `onMouseLeave` handler. React 16.9's `useState` and `useCallback` hooks manage the state updates efficiently.

A React-based SVG visualization demonstrates a circle that follows the cursor across a 960-by-500 viewport. The application tracks the mouse position through the `onMouseMove` event handler, updating state via React’s `useState` and `useCallback` hooks, then re-renders the circle’s center coordinates accordingly. The circle starts at the viewport’s midpoint and moves smoothly to match the pointer’s `clientX` and `clientY` values. The rendering relies on React DOM to mount the SVG element, with no external charting library involved.

A React component renders an SVG circle that follows the mouse cursor across a 960 by 500 pixel canvas. The application uses React state and the `onMouseMove` event handler to track cursor coordinates, updating the circle's `cx` and `cy` attributes in real time. It demonstrates a simple interactive visualization built with React 16 and SVG, where the circle’s position is bound directly to the user’s pointer location.

A React component renders an SVG circle that follows the mouse cursor across a 960-by-500 viewport. The app uses React's `useState` and `useCallback` hooks to track mouse coordinates from the `onMouseMove` event, passing the updated position to the circle's `cx` and `cy` attributes. The visualization demonstrates basic event handling and state-driven SVG rendering in React.

Mouse Follower

A circle follows the mouse cursor across an SVG canvas, updating its position in real time as the pointer moves. The React application tracks the mouse’s client coordinates and renders a single circle centered on that point. It uses the `useState` hook to store the cursor position and the `onMouseMove` event on the SVG element to trigger updates. The visualization is built with React and ReactDOM, rendering SVG directly in the browser with a fixed canvas size of 960 by 500 pixels.

An interactive React and SVG visualization demonstrates mouse tracking by rendering a single black circle that follows the cursor across a 960x500 coordinate space. The app uses the `useState` hook to store the mouse position and a `useCallback`-wrapped event handler to update that state on every SVG `onMouseMove` event. The circle’s center coordinates are bound directly to the current mouse position, producing a seamless, real-time response. The initial position is set to the viewport’s center, and the circle radius is fixed at 30 pixels.
