Mouse Follower

Mouse Follower

A yellow circle follows the mouse cursor across a full-window SVG canvas built with React. The component tracks pointer coordinates via the `onMouseMove` event handler and updates state with `useState`, re-rendering the circle’s `cx` and `cy` attributes on each move. Rendering is handled by ReactDOM and React 16.9, with the SVG viewport sized to `window.innerWidth` and `window.innerHeight`. No external data source is used; the visualization purely demonstrates interactive state-driven positioning.

A yellow circle follows the mouse cursor across a full-window SVG canvas. Built with React and rendered using SVG, the application tracks pointer movements through an `onMouseMove` event handler, updating the circle's `cx` and `cy` coordinates in real time. The code uses React's `useState` and `useCallback` hooks, with the SVG viewport sized to the browser's `window.innerWidth` and `window.innerHeight`.

A yellow circle follows the mouse cursor across an SVG canvas. The visualization tracks pointer movement and repositions the circle to match the cursor’s coordinates in real time. Built with React, it uses the `useState` hook to store the mouse position and an `onMouseMove` event handler on the SVG element to update that state. The circle renders via ReactDOM with SVG markup, and its `cx` and `cy` attributes are bound to the current mouse coordinates.

A yellow circle follows the mouse pointer across an SVG canvas in this React-based visualization. The app tracks mouse movements through the SVG's `onMouseMove` event handler, updating the circle's `cx` and `cy` attributes via React's `useState` hook. The example demonstrates real-time, state-driven rendering using React 16.9 and ReactDOM, with the circle positioned at the cursor's client coordinates on a 960x500 viewport.

A yellow circle follows the mouse cursor across a full-screen SVG canvas. The visualization demonstrates a simple interactive state update in React, where the circle’s position mirrors the cursor’s coordinates in real time. The component uses React’s `useState` hook to track the mouse position and `useCallback` to handle the `onMouseMove` event, updating the circle’s `cx` and `cy` attributes. The SVG rendering is driven entirely by React’s declarative updates, with no additional data source or animation library involved.

A yellow circle follows the mouse as it moves across a blank SVG canvas. The visualization tracks the cursor position in real time, rendering the circle at the exact coordinates of the pointer. Built with React and ReactDOM, it uses SVG’s `onMouseMove` event handler to capture the cursor’s client coordinates and update the circle’s `cx` and `cy` attributes. The circle maintains a constant radius of 30 pixels within a 960 by 500 viewport.

A yellow circle follows the mouse cursor across a full-screen SVG canvas. The React component tracks pointer coordinates via an `onMouseMove` event handler, storing them in state with `useState` and updating the circle’s `cx` and `cy` attributes. The visualization uses `ReactDOM.render` to mount the app, with the circle’s radius fixed at 30 pixels.

A yellow circle follows the mouse cursor across an SVG canvas, updating its position in real time. Built with React and SVG, the app uses a `useState` hook to track mouse coordinates from an `onMouseMove` event handler on the `<svg>` element. The circle radius is fixed at 30 pixels, and the canvas dimensions are 960 by 500, with the initial cursor position centered. The example demonstrates interactive state management and event-driven rendering in a React-based visualization.
