A circle follows the mouse cursor across a large SVG canvas, updating its position in real time based on pointer movement. The example uses React state and the `useState` and `useCallback` hooks to track the mouse coordinates, passing them to the SVG circle’s `cx` and `cy` attributes. Rendering is handled via ReactDOM, with the SVG element listening for `onMouseMove` events to trigger position updates.

MouseFollower

A circle follows the mouse cursor across an SVG canvas, updating its position in real time as the pointer moves. The example uses React state with the `useState` and `useCallback` hooks to track mouse coordinates, which are passed as `cx` and `cy` attributes to a D3 v7-generated circle element. The SVG itself handles mouse movement events via `onMouseMove`, while the ReactDOM library renders the component into the DOM.

Mouse Follower

A circle follows the mouse cursor across an SVG canvas, updating its position in real-time in response to mouse movement. The example demonstrates state management in React, using the `useState` hook to store mouse coordinates and the `useCallback` hook to handle the `onMouseMove` event. The circle is rendered as an SVG `<circle>` element within a React component, with the width and height set to 960 and 500 pixels. The visualization uses React's declarative rendering to update the circle's `cx` and `cy` attributes as the mouse moves.

Mouse Follower

A circle follows the mouse cursor across an SVG canvas. The example demonstrates state management in React, using the `useState` hook to track cursor coordinates and the `useCallback` hook to optimize the mouse move event handler. React renders the circle's position dynamically with a 20-pixel radius, starting at the center of a 960 by 500 viewport. The code uses React 16.9 and ReactDOM to render the SVG element, updating the circle's `cx` and `cy` attributes on every `mousemove` event.

Mouse Follower

A circle follows the mouse cursor across a full-screen SVG canvas, its position updating in real time to mirror the user's movement. The example demonstrates state-driven rendering with React, using the `useState` hook to track cursor coordinates and the `useCallback` hook to handle `mousemove` events efficiently. The SVG is sized to the browser window, and the circle's center is set via `cx` and `cy` properties tied directly to the current mouse position state.

Mouse Follower

A circle follows the mouse cursor across a full-screen SVG canvas, updating its position in real time in response to pointer movement. The React app tracks the mouse coordinates via the `onMouseMove` event handler and stores them in state with `useState`, while `useCallback` memoizes the handler for efficiency. The circle’s center is rendered at the cursor’s `clientX` and `clientY` coordinates, with a fixed radius of 30 pixels, using React and ReactDOM to manage the SVG output.

Mouse Follower

A circle follows the mouse cursor across an SVG canvas, updating its position in real time. Built with React using the `useState` and `useCallback` hooks, the component tracks mouse coordinates via an `onMouseMove` handler and renders the circle with `ReactDOM.render`. The SVG viewport is fixed at 960 by 500 pixels, with no data source or additional visual elements.

Mouse Follower

A circle follows the mouse cursor as it moves across an SVG canvas. The React component tracks pointer coordinates via the `onMouseMove` event and updates the circle’s `cx` and `cy` attributes through `useState` and `useCallback`. Rendered with D3 v5’s SVG helpers within React 16.9, the example demonstrates real-time state-driven positioning without external data.

Mouse Follower

A circle follows the mouse cursor within an SVG canvas, updating its position in real time as the pointer moves. Built with React, the application tracks mouse coordinates using an `onMouseMove` event handler and stores them in state via `useState`. The circle’s `cx` and `cy` attributes are bound to this state, and the SVG is rendered through ReactDOM. D3.js is included but not used for drawing; the interaction relies solely on React’s event system.
