Mouse Follower

Mouse Follower

A React component renders an SVG circle that follows the mouse cursor across a 960 by 500 pixel canvas. The application uses React state and the `onMouseMove` event handler to track cursor coordinates, updating the circle's `cx` and `cy` attributes in real time. It demonstrates a simple interactive visualization built with React 16 and SVG, where the circle’s position is bound directly to the user’s pointer location.

Mouse Follower

A React component tracks the mouse position within an SVG canvas using the `useState` and `useCallback` hooks, rendering a circle that follows the cursor. The `onMouseMove` event handler updates the circle's center coordinates via `setMousePosition`. The SVG circle updates its `cx` and `cy` attributes in real time, demonstrating reactive rendering with React 16.9 and ReactDOM.

A React component renders an SVG circle that tracks the mouse position across a 960 by 500 viewport. The app uses the `useState` hook to store the current cursor coordinates and the `useCallback` hook to handle the `onMouseMove` event on the SVG element. As the pointer moves, the circle’s `cx` and `cy` attributes update reactively via `setMousePosition`, with a fixed radius of 30 pixels. The interaction is purely client-side, with no external data.

A React component renders an SVG circle that follows the mouse cursor across a 960-by-500 viewport. The app uses React's `useState` and `useCallback` hooks to track mouse coordinates from the `onMouseMove` event, passing the updated position to the circle's `cx` and `cy` attributes. The visualization demonstrates basic event handling and state-driven SVG rendering in React.

A React component tracks the mouse position within an SVG canvas, rendering a circle that follows the cursor. The example uses React hooks, specifically useState and useCallback, to manage and update the mouse coordinates, which are assigned to the circle’s cx and cy attributes. The SVG element’s onMouseMove event handler captures clientX and clientY values, and the circle radius is fixed at 50 pixels. The rendering is done entirely through ReactDOM with no external data source.

A circle follows the mouse cursor as it moves across an SVG canvas, updating its position in real time. The visualization uses React state via `useState` and `useCallback` to track mouse coordinates from the `onMouseMove` event, and renders the circle with SVG markup. The React DOM library mounts the component to the page, while the circle’s center is set to the current pointer location. This demonstrates a simple interactive pattern where user input directly drives visual output.

A single black circle follows the mouse cursor across a blank SVG canvas. The React component tracks pointer coordinates via the `onMouseMove` event, updating the circle’s `cx` and `cy` attributes with the client’s position. Using `useState` to hold the origin and `useCallback` for the handler, it re-renders the circle at the new location on every movement. The example demonstrates dynamic SVG updates driven by React state changes without external data.

Mouse Follower

A circle follows the mouse cursor across an SVG canvas, updating its position in real time as the user moves the pointer. The React component uses the `useState` hook to store mouse coordinates and the `useCallback` hook with an `onMouseMove` event handler to update them. It renders a single `<circle>` element with the React DOM, ensuring smooth tracking without any external data source.
