Mouse Follower

Mouse Follower

A single yellow circle follows the mouse cursor across a blank SVG canvas. The React component tracks pointer coordinates through an `onMouseMove` event handler, using the `useState` hook to update the circle’s `cx` and `cy` attributes with each movement. The example demonstrates state-driven, declarative SVG rendering in React, with the circle initialized at the center of the 960×500 viewport and a fixed radius of 30 pixels.

A yellow circle follows the mouse cursor across an SVG canvas, updating its position in real time. The React application uses the `useState` and `useCallback` hooks to track mouse coordinates from the `onMouseMove` event, then renders a single `<circle>` element whose `cx` and `cy` attributes are bound to that state. The circle starts at the canvas center and moves smoothly as the user moves the pointer, with the SVG viewport set to 960 by 500 pixels.

A yellow circle follows the mouse cursor as it moves across a blank SVG canvas. The circle’s position is updated on every mouse-move event, using React’s `useState` and a custom `handleMouseMove` callback. The example uses React and ReactDOM to render an SVG `<circle>` element, with the cursor’s `clientX` and `clientY` coordinates directly mapping to the circle’s `cx` and `cy` attributes. The initial circle is centered at 480, 250 with a radius of 30.

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 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-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 single yellow circle follows the mouse cursor across an SVG canvas, updating its position in real time. The visualization uses React’s `useState` and `useCallback` hooks to track mouse coordinates via the SVG `onMouseMove` event, then re-renders the circle’s `cx` and `cy` attributes. It is built with React 16.9 and rendered as SVG, with the initial circle centered at a fixed width and height of 960 by 500 pixels.

Mouse Follower

A yellow circle follows the mouse cursor across a blank SVG canvas. The example demonstrates mouse tracking in React by updating the circle’s center coordinates on every pointer move. It uses React’s `useState` and `useCallback` hooks, with the `onMouseMove` event handler reading `clientX` and `clientY` from the event object to re-render the circle. The SVG is rendered via ReactDOM, and the initial circle position is centered within a 960×500 viewport.
