A yellow circle follows the mouse cursor across an SVG canvas, with its position updating in real time as the pointer moves. The React component uses the `useState` and `useCallback` hooks to track mouse coordinates via an `onMouseMove` event handler, rendering the circle with dynamic `cx` and `cy` attributes. Built with React 17 and D3 v7, the example demonstrates a simple interactive data-binding pattern without external data sources.

A yellow circle follows the cursor across an SVG canvas, updating its position in real time. Built with React and D3 v7, the visualization uses React's `useState` and `useCallback` hooks to track mouse coordinates via the SVG `onMouseMove` event, then re-renders the circle with the new `cx` and `cy` attributes. The SVG rendering approach keeps the circle's radius constant at 30 pixels.

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 follows the mouse cursor across a blank SVG canvas, updating its position in real time as the pointer moves. The visualization demonstrates a simple React component using the `useState` and `useCallback` hooks to manage and update the circle’s center coordinates, while D3 v5 is loaded via a script tag but not directly used for rendering. Mouse events are captured on the SVG element via `onMouseMove`, and the circle’s `cx` and `cy` attributes are bound to the stored position state.

A yellow circle follows the mouse cursor as it moves across an SVG canvas. The circle updates its position in real time through React’s `useState` and `useCallback` hooks, which handle mouse-move events. The example uses React and D3 v7, rendering the circle as an SVG element with coordinates derived from the `clientX` and `clientY` properties of the mouse event.

A yellow circle with a black outline follows the mouse cursor across an SVG canvas in real time. The React app tracks pointer movements via an `onMouseMove` event handler, storing the cursor’s client coordinates in state with `useState` and `useCallback`. D3 v7 is loaded for potential utility, though the core interaction relies on React’s rendering. The circle’s center position updates reactively, creating a direct, responsive visual link between input and output.

Mouse follower

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.

Mouse Follower

A yellow circle follows the mouse cursor across an SVG canvas. The example demonstrates real-time interaction in a React application, using state management to track the cursor's coordinates. The code builds an SVG with React's `useState` and `useCallback` hooks, updating the circle's `cx` and `cy` attributes on every `onMouseMove` event. The React component renders directly into a `div` element, with the SVG's default styling coming from D3 v5 and React 16.9.0.

Mouse Follower

A yellow circle follows the mouse cursor across a full-screen SVG canvas. The visualization is built with React hooks, using `useState` to track the cursor position and `useCallback` for the mouse-move event handler. The D3 library is available but not actively used; instead, React's rendering updates the circle’s `cx` and `cy` attributes in real time. The example demonstrates simple interactive state management within a React-D3 integration.
