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 960×500 SVG canvas, updating its position in real time through React state. The app uses `useState` to store the current mouse coordinates and `useCallback` to handle `mousemove` events, with the circle’s `cx` and `cy` attributes bound to that state. Rendered via ReactDOM and React 16.9, the visualization demonstrates reactive SVG updates without any external data source.

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.

Mouse Follower

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.

Mouse Follower

A yellow circle follows the mouse cursor as it moves across an empty SVG canvas. The React component tracks pointer coordinates via the `onMouseMove` event and updates the circle's `cx` and `cy` attributes in response. The implementation uses React's `useState` and `useCallback` hooks with ReactDOM to render the SVG, providing an interactive demonstration of mouse tracking without any data source.

A yellow circle follows the mouse cursor across a full-window SVG canvas in this React application. The visualization tracks pointer movement using the SVG `onMouseMove` event, which updates the circle's `cx` and `cy` coordinates in real time. The circle's position is stored in React state and re-rendered on every mouse move, while its radius remains fixed at 50 pixels. The program uses React 16.9 with a custom event handler to create an interactive, responsive display that maps the cursor's screen coordinates directly to the SVG coordinate space.

A yellow circle follows the mouse cursor across a blank SVG canvas. The visualization demonstrates React mouse event handling, with the circle's position updating in real time based on the user's pointer movement. The code uses React's `useState` and `useCallback` hooks within a functional component, rendering an SVG `<circle>` element whose `cx` and `cy` attributes are set from the `clientX` and `clientY` coordinates captured by the `onMouseMove` event. The viewport is fixed at 960 by 500 pixels.

A yellow circle follows the mouse cursor across a full-window SVG canvas. The circle’s position updates in real time to match the cursor’s coordinates, offset slightly down and right. The visualization uses React with the `useState` hook to track mouse movement and re-render the SVG circle on each event. The `onMouseMove` event handler captures `clientX` and `clientY` from the JavaScript `MouseEvent`, and the circle is drawn with a fixed radius of 30 pixels and a fill color of `#fcd947`.
