A circle remains fixed at the center of an SVG while React tracks the mouse position and updates the component's state. The example shows a simple interactive visualization where the cursor's coordinates are captured through the `onMouseMove` event, rendering a static shape rather than moving the circle itself. Using React 16.9 with hooks like `useState` and `useCallback`, it demonstrates a minimal state-driven component structure in ReactDOM, rendering SVG elements with hardcoded dimensions (960×500) and a circle of radius 30 pixels.

Mouse Follower

This example demonstrates how React state can drive an interactive SVG visualization: a single circle follows the mouse cursor across a 960x500 viewport. On every mousemove event on the SVG, the `handleMouseMove` callback updates the `mousePosition` state with the cursor’s client coordinates, and React re-renders the circle’s `cx` and `cy` attributes accordingly. It uses React 16.9 with hooks (`useState`, `useCallback`) and renders directly to SVG via `ReactDOM.render`.

Mouse Follower

This example demonstrates a simple interactive visualization where a circle follows the mouse cursor within an SVG canvas. It shows how React state can track pointer position and update visual elements in real-time. The code uses React’s `useState` and `useCallback` hooks to manage the mouse coordinates from the `onMouseMove` event, and renders a single circle element with dynamic `cx` and `cy` attributes. The visualization is built with React 16.9 and rendered as SVG, with the circle starting at the center of a 960×500 pixel viewport.

Mouse Follower

A circle follows the mouse cursor across an SVG canvas. The example demonstrates state management in React, using the `useState` hook to track cursor coordinates and the `useCallback` hook to optimize the mouse move event handler. React renders the circle's position dynamically with a 20-pixel radius, starting at the center of a 960 by 500 viewport. The code uses React 16.9 and ReactDOM to render the SVG element, updating the circle's `cx` and `cy` attributes on every `mousemove` event.

Mouse Follower

A React component renders an SVG circle that follows the mouse pointer across a 960 by 500 viewport. The circle’s center coordinates are updated via React’s `useState` hook and a `handleMouseMove` callback attached to the SVG’s `onMouseMove` event. The `useCallback` hook memoizes the event handler, and `ReactDOM.render` mounts the app. The visualization demonstrates basic state-driven interactivity without external data, using only React and SVG primitives.

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 example demonstrates React's state management and event handling, using the `useState` hook to track mouse coordinates and an `onMouseMove` event listener on the SVG element. ReactDOM renders the component, which draws a navy circle with a radius of 30 pixels against a blank white background. The visualization highlights a simple interactive pattern with minimal code, relying solely on React's declarative rendering rather than any additional libraries.

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.

Mouse Follower

A circle, initially positioned at the center of an SVG canvas, follows the mouse cursor across the screen. The React component renders the circle with fixed initial coordinates and relies on React’s virtual DOM to update its position dynamically. Using React 16.9 and ReactDOM, the example demonstrates basic state-driven rendering without external event listeners. The circle’s movement is implied by React’s re-rendering, though the code shown lacks a mouse event handler. It serves as a minimal illustration of SVG integration within a React application.

Mouse Follower

This example uses React to render an SVG circle that follows the mouse cursor across the screen. The `index.js` file initializes a React state hook with the circle’s coordinates, then updates that state on every `onMouseMove` event triggered on the SVG element. The circle’s position is bound directly to the current mouse coordinates via the `cx` and `cy` attributes, with a fixed radius of 30 pixels. The visualization relies on React’s `useState` and `useCallback` hooks, along with `ReactDOM.render` to mount the component.
