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 single yellow circle follows the mouse cursor across an SVG canvas. The visualization uses React state to track the cursor's clientX and clientY coordinates and passes them as the circle's cx and cy attributes. The index.js file imports React's useState and useCallback hooks, while D3 is loaded but not directly used in the visible logic. The example demonstrates a lightweight approach to binding mouse events to SVG elements within a React component structure.

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 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.

Mouse Follower

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.

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 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.

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 follows the cursor across an SVG canvas, updating its center position in real time as the mouse moves. The visualization uses React's state management with an `onMouseMove` event handler to track client coordinates, while D3.js provides the SVG rendering environment. The circle's position is bound to the mouse coordinates via React's `useState` and `useCallback`, creating a direct one-to-one mapping between input and visual output.
