A single dark circle moves within an SVG viewport in direct response to the mouse cursor. The example demonstrates a simple React state update mechanism: the `onMouseMove` event on the `<svg>` element captures cursor coordinates, which are stored in `mousePosition` via `React.useState` and applied to the circle’s `cx` and `cy` attributes. The initial position is centered at (480, 250), and the circle’s radius is set to 10% of the viewport height. Crafted with React 17 and ReactDOM, it renders a pure SVG without external data or animation libraries.

Mouse Follower

A single dark circle tracks the cursor’s movement across a 960×500 SVG canvas. The circle’s center is repositioned directly to the mouse’s client coordinates on every move event, using React state updates triggered by the SVG’s `onMouseMove` handler. Built with React and ReactDOM, the example renders purely through SVG elements, with the circle maintaining a constant radius of 30 pixels while following the pointer smoothly across the viewport. The code initializes the circle at the canvas center before any mouse activity occurs.

Mouse Follower

A single dark circle follows the mouse cursor across an SVG canvas in a React-based visualization. The circle’s position updates live via React’s `useState` hook, driven by the SVG `onMouseMove` event, which captures the cursor’s client coordinates. Rendering uses plain SVG elements, with D3 v5 loaded but not actively used in the logic. The example demonstrates reactive state-driven updates in React for interactive graphics, with the circle centered on the pointer’s exact location.

Mouse Follower

A React-controlled SVG circle follows the mouse cursor across a fixed 960×500 viewport. Mouse coordinates are captured by the SVG’s `onMouseMove` event, processed via a `useCallback` hook, and stored in React state with `useState`. Each movement updates the circle’s `cx` and `cy` attributes, causing a re-render. The example demonstrates direct state-driven SVG updates without D3-specific interaction APIs, relying solely on React’s event handling and DOM reconciliation.

Mouse Follower

A circle follows the mouse cursor inside an SVG canvas, updating its position in real time as the user moves over the 960×500 drawing area. The example demonstrates React state management with `useState` and event handling via the `onMouseMove` callback, rendering the circle as an SVG `<circle>` element. It uses React 16.9 and ReactDOM to mount the component, with the circle’s coordinates derived directly from the browser’s `clientX` and `clientY` event properties.

Mouse Follower

A React mouse follower tracks the cursor’s position within an SVG canvas. A circle responds instantly to every mouse move, updating its coordinates via React state and the `onMouseMove` handler. The example uses React’s `useState` and `useCallback` hooks, rendering a single `<circle>` element inside an SVG with fixed dimensions. The initial position is centered, and the circle follows the mouse from there, demonstrating simple event-driven rendering with React and SVG.

Mouse follower

A single circle follows the mouse cursor within an SVG canvas. The circle’s position is updated via React state, triggered by an `onMouseMove` handler that tracks `clientX` and `clientY` coordinates. The example uses React 16.9 with hooks (`useState`, `useCallback`) and renders the SVG element with the circle’s `cx` and `cy` attributes bound to the current mouse position. The visualization demonstrates a simple interactive pattern with minimal code, relying solely on React’s state management and SVG rendering.

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 960-by-500 SVG circle follows the mouse cursor across the canvas, its center updating in real time to match the pointer’s client coordinates. Built with React and ReactDOM, the example uses the `useState` hook to store the cursor position and a `useCallback`-wrapped `onMouseMove` event handler to update it. The SVG circle is rendered with a fixed radius of 30 pixels, demonstrating state-driven drawing within a minimal React component.
