A yellow circle follows the mouse cursor across an SVG canvas. The interface tracks pointer movement and repositions the circle to match the cursor’s coordinates. Built with React (using `useState` and `useCallback`), the SVG reacts to `onMouseMove` events. D3.js version 5 provides the SVG rendering context, while React manages the state updates.

A yellow circle with a black outline follows the mouse cursor across an SVG canvas. The React component tracks pointer movement via an `onMouseMove` event handler, storing coordinates in state with `useState` and updating them through `useCallback`. D3 v7 is included but not directly used for the interaction; React 18 handles rendering and state updates. The initial circle position is centered within the 900×560 viewport before the cursor enters the SVG area.

A yellow circle follows the mouse cursor across a blank SVG canvas, with its position updating in real time to track pointer movement. The visualization demonstrates React state management for interactive graphics, using React hooks `useState` and `useCallback` to handle mouse events. The `onMouseMove` handler on the SVG element captures cursor coordinates, which are then used to set the circle's `cx` and `cy` attributes. Built with React 16.9.0 and D3.js v6, the example renders entirely through React's virtual DOM without direct D3 DOM manipulation.

A yellow circle tracks the mouse cursor across a fixed-width SVG canvas, with its position updating in real time based on pointer movement. The visualization demonstrates the integration of React state management with D3’s SVG rendering capabilities. It uses React’s `useState` hook to store and update the cursor coordinates, which are passed as `cx` and `cy` attributes to a D3-created circle element. The `onMouseMove` event handler on the SVG container triggers state changes, while D3’s `arc` function is imported though unused.

A yellow circle follows the mouse cursor inside an SVG canvas. The example demonstrates React state management with a `useState` hook to track the cursor's `clientX` and `clientY` coordinates, updating on every `onMouseMove` event. The app renders a single `<circle>` element with a radius of 30, initially centered at a fixed midpoint, and uses React's `useCallback` to optimize the handler. Built with React 16.9 and D3 v5, the rendering relies entirely on SVG output without external data sources.

A yellow circle tracks the mouse cursor in real time within an SVG canvas, using React to manage the circle's position as state. The `App` component listens to `onMouseMove` events on the SVG element, updating the circle's `cx` and `cy` attributes via `useState` and `useCallback`. The example integrates React with D3 for SVG rendering, with the circle initially centered at 480,250.

A yellow circle follows the mouse cursor across a blank SVG canvas, tracking every movement in real time. The visualization demonstrates React state management, where mouse coordinates update the circle's position via the `useState` and `useCallback` hooks. Rendered as an SVG element, the circle's `cx` and `cy` attributes are bound to the current cursor position. The example uses React 16.9 and D3 v5, with the D3 `arc` function imported but unused, relying instead on React's event handling for interactivity.

A yellow circle tracks the user's mouse cursor across an SVG canvas, updating its position in real time. The React app listens for mouse-move events through an SVG `onMouseMove` handler, storing coordinates in state. D3.js renders the circle, while React's `useState` and `useCallback` manage the dynamic positioning.
