A React SVG circle follows the mouse cursor across the full browser window, updating its position in real time. The app uses React’s `useState` and `useCallback` hooks to track the cursor’s `clientX` and `clientY` coordinates, storing them in a state object. The `onMouseMove` event handler on the `<svg>` element triggers a state update, and the circle’s `cx` and `cy` attributes re-render with the new position. The example demonstrates declarative interaction between React state and SVG rendering without external data or animation libraries.

Mouse follower

A React component uses SVG to draw a circle that follows the mouse cursor across the full browser window. The circle’s position is tracked via the `onMouseMove` event handler, which updates React state with the cursor’s `clientX` and `clientY` coordinates. The SVG viewport matches the window’s inner width and height, and the circle is re-rendered with a fixed radius at the updated position. The example demonstrates declarative UI updates driven by user input, using React’s `useState` and `useCallback` hooks.

Mouse follower

A React application renders a single SVG circle that follows the mouse cursor as it moves across the full-window viewport. The component uses the `useState` and `useCallback` hooks to track the cursor’s `clientX` and `clientY` coordinates, updating the circle’s `cx` and `cy` attributes on every `onMouseMove` event. The initial position is centered based on `window.innerWidth` and `window.innerHeight`. This simple interactive example demonstrates real-time state-driven SVG updates without any external data sources or animation libraries.

Mouse follower

A circle follows the cursor as it moves across an SVG canvas. The example uses React’s `useState` and `useCallback` hooks to track mouse coordinates from the `onMouseMove` event, updating the circle’s `cx` and `cy` attributes in real time. The SVG’s width is fixed at 960 pixels and height at 500, with the initial position centered. The rendering is done entirely through React’s declarative component structure, producing a simple interactive visualization without any external data sources.

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 single circle follows the mouse cursor within an SVG canvas. The circle’s position is updated via React state, triggered by an `onMouseMove` handler that tracks `clientX` and `clientY` coordinates. The example uses React 16.9 with hooks (`useState`, `useCallback`) and renders the SVG element with the circle’s `cx` and `cy` attributes bound to the current mouse position. The visualization demonstrates a simple interactive pattern with minimal code, relying solely on React’s state management and SVG rendering.

Mouse Follower

This example shows a single circle that follows the mouse cursor across the full browser window. The circle’s position updates live through React state, using the `clientX` and `clientY` values from the `onMouseMove` event on an SVG element. The code renders the circle as an SVG `<circle>` with React 16.9, and the state hook `useState` manages the cursor coordinates. The visualization demonstrates a simple interactive mapping between pointer movement and SVG shape placement.

Mouse Follower

A React-controlled SVG circle follows the mouse cursor across a fixed 960×500 viewport. Mouse coordinates are captured by the SVG’s `onMouseMove` event, processed via a `useCallback` hook, and stored in React state with `useState`. Each movement updates the circle’s `cx` and `cy` attributes, causing a re-render. The example demonstrates direct state-driven SVG updates without D3-specific interaction APIs, relying solely on React’s event handling and DOM reconciliation.

Mouse follower, a circle

A circle follows the mouse cursor across a full-screen SVG canvas, with its position updating live in response to pointer movement. The visualization demonstrates interactive React state management, where the initial mouse position is set to the center of the window. Using React's `useState` hook and an SVG `onMouseMove` event handler, the component captures `clientX` and `clientY` coordinates from the event to update the circle's `cx` and `cy` attributes. The code relies on React 16.9 and ReactDOM to render the circle element.
