A React application renders a single black circle that follows the mouse cursor across the full browser window. The circle’s position updates in real time using React’s `useState` and `useCallback` hooks, driven by an `onMouseMove` event on an SVG element. The SVG canvas sizes itself to `window.innerWidth` and `window.innerHeight`, and the circle starts at the screen’s center. The code relies on React 16.9 and ReactDOM to mount the component, with no additional data sources or rendering libraries beyond plain SVG.

follow the mouse

A React SVG renders a single black circle that follows the mouse cursor across the full browser window. The component tracks pointer position via the `onMouseMove` event, storing coordinates in state with `useState` and updating them through `useCallback`. The circle's `cx` and `cy` attributes are bound to the current mouse coordinates, redrawing on every move. This example demonstrates real-time interaction between user input and SVG elements using React's declarative rendering.

Mouse follow

A React mouse-follow example renders a single SVG circle that tracks the cursor in real time. As the pointer moves across the full-window SVG, the circle's center coordinates update via React state and the `onMouseMove` event handler. Built with React 16.9 and no external data, it demonstrates a minimal interactive component using `useState` and `useCallback` to manage position updates.

Mouse follower

A React application renders a full-screen SVG that tracks the mouse cursor with a black circle. The component uses React hooks `useState` and `useCallback` to store and update the cursor position on every `mousemove` event, and re-renders the SVG circle’s `cx` and `cy` attributes accordingly. The SVG’s width and height are set to the browser window dimensions, and the circle’s radius is fixed at 30 pixels. ReactDOM is used to mount the component into the DOM, with no external data source beyond the user’s pointer movement.

React Interaction

A black circle follows the mouse cursor across a full-window SVG canvas, and toggles its tracking on and off with each click. Built with React and ReactDOM, the example uses the `useState` hook to manage the position and active state, while `onMouseMove` and `onClick` handlers update the circle's coordinates. The SVG is rendered directly in the browser window, with no external data source.

Mouse Move React

A React SVG visualization tracks the mouse position within a 960 by 500 viewport. It renders a single circle that follows the cursor, using React’s `useState` to store coordinates and `useCallback` to optimize the mouse-move handler. The circle’s center updates directly from the event’s `clientX` and `clientY` values, demonstrating a minimal interactive component built with React 16 and rendered through `ReactDOM.render`.

Mouse Follower

A React and SVG visualization renders a single black circle that follows the mouse cursor across a 960 by 500 pixel canvas. The circle’s position updates in response to mouse movement events handled through React’s `onMouseMove` callback, with state managed via the `useState` hook. The application uses ReactDOM to render the SVG element, and the circle’s center coordinates are dynamically set to the cursor’s client-space position, creating a direct and immediate tracking effect.

Mouse follower

A React component renders an SVG circle that follows the mouse pointer across a 960×500 viewport. On every mouse move, the `onMouseMove` event handler updates the circle’s `cx` and `cy` coordinates via React’s `useState` and `useCallback` hooks. The circle starts centered and has a fixed radius of 30 pixels. The example demonstrates interactive SVG rendering with React, using only ReactDOM and no external data or visualization libraries.

React Draw with Mouse

A React component renders an SVG circle that follows the mouse pointer across a 960×500 canvas. The SVG’s `onMouseMove` event updates React state via `useState`, and `useCallback` memoizes the handler to prevent unnecessary re-renders. The circle’s `cx` and `cy` coordinates are bound to the current mouse position, demonstrating a reactive, declarative drawing interaction. Unlike D3, this example relies solely on React’s state management and SVG’s native event handling to create a live, mouse-driven visualization.
