A circle follows the mouse cursor across an SVG canvas, updating its position in real time as the pointer moves. Built with React and d3.v7, the app uses React’s `useState` and `useCallback` hooks to track and update the mouse coordinates on every `onMouseMove` event, rendering a single `<circle>` element with a radius of 30 pixels. The example relies on SVG rendering within a 960×500 viewport, with the initial circle centered at the midpoint of the canvas.

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.

Circle Follower Mouse

A circle follows the mouse cursor across an SVG canvas. The visualization tracks pointer movement and updates the circle's position in real time. Built with React and SVG, it uses React's `useState` and `useCallback` hooks to manage the cursor coordinates. A `handleMouseMove` callback on the SVG element captures `event.clientX` and `event.clientY` values, which are then passed to the circle's `cx` and `cy` attributes. The circle starts centered in the 960×500 viewport and responds immediately to any mouse movement, creating a direct interactive feedback loop.

Mouse follower

A circle follows the mouse cursor across an SVG canvas, creating a simple interactive visual response. The React application tracks cursor position through an `onMouseMove` event handler, updating state via the `useState` and `useCallback` hooks, and renders the circle using D3 v7 within an SVG element. The circle’s center coordinates are dynamically bound to the latest mouse position, with a fixed radius of 30 pixels.

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.

Mouse Follower

A circle follows the cursor across an SVG canvas, updating its position in real time as the mouse moves. Built with React and D3 v7, the visualization uses React's `useState` hook to store the mouse coordinates and a `useCallback` handler to update them on every `onMouseMove` event. The circle is rendered as an SVG `<circle>` element, with its `cx` and `cy` attributes bound directly to the current mouse position, creating a smooth, direct response to user input.

Mouse Follower

A circle follows the mouse cursor across a full-screen SVG canvas. The circle's position is bound to the mouse coordinates, updated on every mouse move event. The example uses React with a `useState` hook to manage the cursor position, and the ReactDOM `render` method to mount the component. D3.js is loaded but not actively used in the rendering logic, which relies solely on native SVG elements and React event handling. The circle is drawn with a fixed radius of 30 pixels.

Mouse Follower

A circle inside an SVG follows the mouse cursor in real time. The visualization tracks pointer coordinates and updates the circle's position instantly. Built with React and D3 v7, the app uses the `onMouseMove` event and the `useState` hook to store and render the cursor's `clientX` and `clientY` values. The circle's radius is fixed at 30 pixels.

MouseFollower

A circle follows the mouse cursor across an SVG canvas in real time. The React component tracks pointer coordinates through the SVG `onMouseMove` event handler, updating the circle’s `cx` and `cy` attributes. Using React hooks like `useState` and `useCallback`, the app re-renders only on cursor movement, while D3 v5 is loaded but unused in this minimal interaction. The initial mouse position is centered at (480, 250) within a 960 by 500 viewport, with the circle’s radius set to 30 pixels.
