A circle follows the mouse pointer across an SVG canvas, updating its center position in real time to mirror the cursor's location. The React component uses a `useState` hook to track mouse coordinates and a `useCallback` handler on the SVG element's `onMouseMove` event. The circle is rendered with a D3.js arc path, though the simple shape relies on React's declarative SVG attributes for positioning, with no external data source.

Mouse Follower

A circle follows the mouse cursor across an SVG canvas, updating its position in real time to mirror the pointer's movement. The React component tracks mouse coordinates through the `onMouseMove` event handler, storing them in state with the `useState` hook and updating via `useCallback`. The circle is rendered as an SVG `<circle>` element, with its `cx` and `cy` attributes driven by the current mouse position.

Mouse Follower

A circle follows the mouse cursor across an SVG canvas, updating its position in real time to mirror the pointer’s movement. The visualization uses React’s `useState` and `useCallback` hooks to track cursor coordinates (`clientX`, `clientY`) and re-render the circle’s `cx` and `cy` attributes on every mouse move. The SVG element handles the `onMouseMove` event, while the circle’s radius is fixed at 30 pixels. The code imports React, ReactDOM, and D3 v5, though no D3-specific functions are invoked beyond the library’s inclusion.

Mouse Follower

A circle follows the mouse cursor within an SVG canvas, updating its position in real time to mirror the pointer's movement. The visualization demonstrates state management and event handling in a React application, where the mouse position is tracked via the SVG's `onMouseMove` event and stored in React state. The circle is rendered as an SVG `<circle>` element, with its `cx` and `cy` attributes bound to the current mouse coordinates. The code uses React Hooks, specifically `useState` and `useCallback`, alongside D3 v5 for SVG creation, all within a React 16.9 framework.

Mouse Follower

A circle follows the mouse cursor across an SVG canvas, updating its position in real time as the pointer moves. Built with React, the app uses the `useState` hook to store the mouse coordinates and a `useCallback` handler triggered by the SVG's `onMouseMove` event. The circle is rendered as an SVG `<circle>` element with a fixed radius of 30 pixels. The viewport is set to 960 by 500 pixels, and the initial position is centered before any mouse movement occurs.

Mouse Follower

A circle follows the mouse cursor across an SVG canvas, updating its position in real time. The example uses React's `useState` and `useCallback` hooks to manage mouse coordinates, with the `onMouseMove` event handler updating the circle's center. D3's `arc` module is imported but not used, while the SVG `<circle>` element is rendered directly through ReactDOM. The visualization demonstrates a simple interactive pattern without any data source or animation logic beyond direct mouse tracking.

Mouse Follower

A circle follows the mouse cursor across an SVG canvas, updating its position in real time to mirror the user’s pointer movements. The visualization uses React’s `useState` and `useCallback` hooks to manage the cursor’s coordinates, captured through the `onMouseMove` event on the `<svg>` element. The circle is rendered via ReactDOM, with its center tied to the `clientX` and `clientY` values from the event, demonstrating a straightforward state-driven interactive graphic.

Mouse Follower

A circle follows the mouse cursor across an SVG canvas, updating its position in real time as the user moves the pointer. The React component uses the `useState` hook to store mouse coordinates and the `useCallback` hook with an `onMouseMove` event handler to update them. It renders a single `<circle>` element with the React DOM, ensuring smooth tracking without any external data source.

Mouse follower

A circle follows the mouse cursor across an SVG canvas, updating its position in real time to mirror the user's pointer movement. The visualization uses React state management with the `useState` and `useCallback` hooks to track the cursor's client coordinates, which are then passed to the circle's `cx` and `cy` attributes. Rendered via ReactDOM, the SVG element listens for `onMouseMove` events to trigger the position updates, creating a simple interactive demonstration of dynamic component re-rendering within a React-based visualization.
