A small yellow circle tracks the mouse cursor across a blank SVG canvas in real time. The example demonstrates a simple interactive follower effect, where the circle’s center coordinates update on every mouse movement event. Built with React and D3.js v5, it uses `useState` to store cursor position and an SVG `onMouseMove` handler to trigger state changes. The rendering approach is purely declarative, with the circle’s `cx` and `cy` attributes directly bound to the current mouse coordinates, and D3 is imported but not used beyond the basic setup.

Mouse Follower

A yellow circle follows the mouse cursor across a blank, full-window SVG canvas. The example demonstrates a simple interactive mouse-follower pattern where the circle’s center position is updated in real-time based on pointer movement. Built with React and D3 v5, it uses React’s `useState` hook to track mouse coordinates from an `onMouseMove` event, then renders the circle via SVG. D3 is imported solely for its `arc` function, though it is not used for the visualization’s core behavior.

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 single yellow circle follows the mouse cursor across an SVG canvas. The example combines React state management with D3’s rendering capabilities, using the `useState` hook to track cursor coordinates and an SVG `onMouseMove` event handler to update them. The circle’s position is updated reactively on every mouse movement, demonstrating a simple interactive data binding between user input and a rendered visual element. The code imports React and ReactDOM directly, while D3 v5 is loaded via a CDN script tag for integration.

Mouse Follower

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.

Mouse Follower

A yellow circle with a black outline follows the mouse cursor across a blank SVG canvas, responding in real time to pointer movement. The visualization is built with React, using the `useState` hook to store the cursor's coordinates and an `onMouseMove` event handler to update them. D3.js is loaded for its utility functions, and the circle is rendered as an SVG element with ReactDOM, providing a simple demonstration of interactive state-driven rendering.

Mouse Follower

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 inside an SVG canvas, updating its position in real time to mirror the pointer’s coordinates. The example demonstrates React’s `useState` and `useCallback` hooks to manage the cursor’s x and y values, while the `onMouseMove` event on the SVG element triggers the state update. Rendered using React DOM with D3 v5, the circle’s radius is fixed at 30 pixels, and its center is bound to the tracked mouse position.

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.
