Mouse follower

A yellow-bordered circle follows the mouse cursor as it moves across an SVG canvas. The circle's position is bound to the mouse's coordinates, which are tracked via the `onMouseMove` event handler. This example uses React's `useState` and `useCallback` hooks to manage and update the cursor position, with the SVG rendered through ReactDOM. The visualization demonstrates a simple interactive mouse-following mechanic without additional data.

A yellow circle follows the mouse cursor inside an SVG canvas, updating its position in real time as the cursor moves. The example is built with React, using the `useState` hook to store mouse coordinates and an `onMouseMove` event handler on the SVG element to capture `clientX` and `clientY` values. The circle’s center is set to those coordinates, and the SVG’s width and height are fixed at 960 by 500 pixels.

A yellow SVG circle follows the cursor across a 960 by 500 canvas. The example demonstrates interactive state management in React, using a `useState` hook to track mouse coordinates and update the circle’s position on every move event. The SVG element listens for `onMouseMove`, and React DOM renders the circle’s `cx` and `cy` attributes based on the stored position. The code relies on React 16.9 and ReactDOM, with the SVG markup embedded directly in the JavaScript.

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 with a black outline follows the mouse cursor across a 960-by-500 SVG canvas. The example uses React's `useState` and a callback to track the cursor's `clientX` and `clientY` coordinates, updating the circle's `cx` and `cy` attributes directly on mouse movement. This demonstrates interactive SVG rendering within a React component, with the circle’s position driven entirely by user input.

A yellow circle follows the mouse cursor across an SVG canvas. The visualization tracks pointer movement and repositions the circle to match the cursor’s coordinates in real time. Built with React, it uses the `useState` hook to store the mouse position and an `onMouseMove` event handler on the SVG element to update that state. The circle renders via ReactDOM with SVG markup, and its `cx` and `cy` attributes are bound to the current mouse coordinates.

A yellow circle follows the mouse cursor across a full-screen SVG canvas. The visualization demonstrates a simple interactive state update in React, where the circle’s position mirrors the cursor’s coordinates in real time. The component uses React’s `useState` hook to track the mouse position and `useCallback` to handle the `onMouseMove` event, updating the circle’s `cx` and `cy` attributes. The SVG rendering is driven entirely by React’s declarative updates, with no additional data source or animation library involved.
