Mouse Follower

Mouse Follower

A full-screen SVG circle follows the mouse cursor in real time, with its center tied directly to the pointer’s clientX and clientY coordinates. Built with React, the example uses the `useState` and `useCallback` hooks to track mouse position and update the circle’s `cx` and `cy` attributes on every move. Rendering is handled via ReactDOM to an SVG element that spans the entire browser window, with no explicit data source beyond user input.

Mouse Follower

A full-screen React SVG component renders a single circle that follows the mouse as it moves. The app tracks mouse coordinates using React's `useState` hook and handles `onMouseMove` events on the SVG element, updating the circle's `cx` and `cy` attributes in real time. The initial position is centered in the window, and the circle radius is fixed at 30 pixels. No external data source is used; the visualization simply demonstrates interactive state-driven rendering with React and SVG.

Mouse Follower

A full-screen SVG circle tracks the mouse in real time. It demonstrates React state management and event handling by updating the circle’s coordinates on every pointer movement. The application uses React’s `useState` and `useCallback` hooks within a functional component, rendering a single `<circle>` element inside an `<svg>` that covers the viewport. The `onMouseMove` event triggers a state update with the cursor’s `clientX` and `clientY` positions, causing React to re-render the circle at the new location.

A circle follows the mouse cursor across a large SVG canvas, updating its position in real time based on pointer movement. The example uses React state and the `useState` and `useCallback` hooks to track the mouse coordinates, passing them to the SVG circle’s `cx` and `cy` attributes. Rendering is handled via ReactDOM, with the SVG element listening for `onMouseMove` events to trigger position updates.

Mouse Follower

A full-screen SVG circle follows the mouse cursor as it moves across the viewport, using React state to track the pointer's coordinates. The component updates the circle's `cx` and `cy` attributes on every `mousemove` event via an `onMouseMove` handler, storing the position with `useState` and `useCallback`. React and ReactDOM render the interactive graphic at 960 by 500 pixels.

A circle follows the mouse cursor across a full-screen SVG, changing position live as the pointer moves. The visualization uses React state and the `useState` hook to track mouse coordinates, with a `useCallback` handler for `onMouseMove` events on the SVG element. The circle’s center is set to the cursor’s client coordinates, and its fixed radius of 30 pixels is defined as a constant. The example demonstrates a minimal React-rendered interactive graphic without external data sources or charting libraries.

Mouse Follower

A single circle in an SVG viewport tracks the user's mouse in real time, following its position across the full screen. Built with React, the app uses the `useState` hook to store the current mouse coordinates and the `useCallback` hook to update them via the SVG `onMouseMove` event handler. The circle’s `cx` and `cy` attributes are bound directly to this state, causing a re-render on every pointer movement. The rendering approach is purely declarative, with the circle’s radius fixed at 30 pixels.

Mouse Follower

A circle follows the mouse cursor across a full-screen SVG canvas, its position updating in real time to mirror the user's movement. The example demonstrates state-driven rendering with React, using the `useState` hook to track cursor coordinates and the `useCallback` hook to handle `mousemove` events efficiently. The SVG is sized to the browser window, and the circle's center is set via `cx` and `cy` properties tied directly to the current mouse position state.
