A mouse follower demonstrates real-time pointer tracking within an SVG canvas using React state. As the user moves the mouse over the 800×800 viewport, a circle smoothly repositions itself to match the cursor’s x and y coordinates. The component uses React’s `useState` hook to store the mouse position and `useCallback` to handle the `onMouseMove` event efficiently. While the code includes D3 v7 as a dependency, the interaction itself relies purely on React’s event handling system, not on D3-specific visualization APIs.

Mouse Follower

A mouse follower example renders a single SVG circle that tracks the cursor's position within a 960 by 500 viewport. Using React state hooks (`useState` and `useCallback`), the component updates the circle's `cx` and `cy` coordinates on every `mousemove` event. D3 version 7 is loaded for potential utilities, though the interaction relies solely on React's event handling and SVG rendering. The circle starts centered and moves fluidly, demonstrating simple interaction between DOM events and React's declarative UI updates.

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 tracks the mouse cursor across a 960 by 500 SVG canvas, updating its position in real time as the user moves the pointer. The React component uses `useState` to store the mouse coordinates and `useCallback` to handle the `onMouseMove` event, passing the event's `clientX` and `clientY` values to reposition the circle via its `cx` and `cy` attributes. It renders with React 17 and D3 v7.

Mouse Follower

A circle follows the mouse cursor across an SVG canvas in this React-based visualization. The app tracks pointer coordinates using a React `onMouseMove` event handler and stores them in component state with the `useState` hook. Each mouse movement updates the circle’s `cx` and `cy` attributes, repositioning it instantly at the cursor’s location. The visualization uses React 16.9 and D3 v5 for rendering, with the SVG circle set to a fixed radius of 30 pixels. No data source is involved; the interaction is purely driven by user input.

Mouse Follower

A circle follows the mouse cursor as it moves across an SVG canvas, creating a simple interactive pointer-tracking effect. The visualization uses React state to store the cursor's coordinates and updates the circle's position through an `onMouseMove` event handler. Rendered with D3 v7 and React 18, the SVG circle has an aquamarine fill with a green stroke. The code relies on React's `useState` and `useCallback` hooks to manage and update the mouse position efficiently.

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.

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

An interactive SVG visualization renders a single circle that follows the mouse cursor across a 960-by-500 canvas. The React component tracks pointer movement via the `onMouseMove` event and updates the circle’s `cx` and `cy` attributes through `useState` and `useCallback`. Initially positioned at the canvas center, the circle moves smoothly with the cursor. The example demonstrates state-driven rendering in React 17 with D3 v7, using plain SVG elements rather than data joins or scales. No external data source is involved; the visualization purely reacts to user input.
