Mouse Follower

Mouse Follower

A circle follows the mouse cursor across an SVG canvas. The visualization uses React's `useState` hook to track the cursor's current coordinates, updating the circle's `cx` and `cy` attributes on every mouse move event. The React component renders the SVG directly, with the circle's position bound to the state value. The canvas is set to a fixed width and height, and the mouse position is captured via the SVG's `onMouseMove` handler. Both React and ReactDOM are loaded from UMD packages.

A circle follows the user's mouse cursor across a full-window SVG canvas, updating its position in real time. The visualization demonstrates React state management with the `useState` and `useCallback` hooks, where a `mousemove` event handler on the SVG element captures client coordinates. ReactDOM renders the circle at the stored mouse position, with the window dimensions defining the SVG's width and height. The code uses React 16.9 and renders purely with SVG elements, with no external data source.

A circle follows the mouse cursor inside an SVG canvas. The visualization shows the cursor's position in real time, updating the circle's center coordinates as the mouse moves. The React application uses the `useState` hook to store mouse coordinates and the `useCallback` hook to handle the `onMouseMove` event on the SVG element. The circle is rendered with SVG, and ReactDOM renders the component into the HTML root element.

A circle follows the mouse cursor within an SVG canvas. The visualization updates the circle's position in real time as the mouse moves. Built with React, it uses the `useState` hook to store the current mouse coordinates and the `useCallback` hook to handle the `onMouseMove` event, updating the circle's `cx` and `cy` attributes accordingly. This example demonstrates interactive data binding and event-driven rendering in React with SVG.

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 circle follows the mouse cursor across a blank SVG canvas. The visualization uses React state to track the cursor's coordinates and updates the circle's position on every mouse move event. It renders via SVG, with React's `useState` hook storing the x and y position and `useCallback` handling the move event listener. The circle is drawn with a fixed radius of 30 pixels, and the mouse position is initialized to the center of the 960 by 500 pixel viewport.
