Mouse Follower

Mouse Follower

A circle follows the mouse cursor within an SVG canvas, with its center position updating live to match the pointer's coordinates. The visualization uses React's `useState` and `useCallback` hooks to manage cursor tracking, while `ReactDOM` renders the SVG element and its circle to the page. The SVG's `onMouseMove` event handler captures the cursor position, and the circle's `cx` and `cy` attributes are updated accordingly with a fixed radius of 30 pixels.

Mouse Follower

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.

Mouse Follower

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.

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.

Mouse Follower

A circle follows the mouse cursor across an SVG canvas as the user moves the pointer. The React component tracks the cursor’s `clientX` and `clientY` coordinates through an `onMouseMove` event handler, updating the circle’s `cx` and `cy` attributes via the `useState` and the component state. The visualization uses React 16.9 and ReactDOM to render the graph, with the SVG resized to 960 by 500 pixels and a constant circle radius of 30.

Mouse Follower

A circle follows the mouse cursor across an SVG canvas, updating its position in real time as the pointer moves. Built with React, the app uses the `useState` hook to store the mouse coordinates and a `useCallback` handler triggered by the SVG's `onMouseMove` event. The circle is rendered as an SVG `<circle>` element with a fixed radius of 30 pixels. The viewport is set to 960 by 500 pixels, and the initial position is centered before any mouse movement occurs.
