A circle follows the mouse cursor inside an SVG canvas. The example demonstrates React's state management and event handling by updating the circle's center coordinates on every mouse move. Built with React 16.9 and ReactDOM, it uses the `useState` hook to store the mouse position and the `onMouseMove` event to update it. The circle's `cx` and `cy` attributes are bound directly to the state, causing the SVG to re-render responsively.

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.

Circle following Mouse

A circle follows the cursor’s position across a 960x500 SVG canvas. Built with React and D3 v7, the example uses an `onMouseMove` event handler on the `<svg>` element to capture mouse coordinates and update React state. The circle’s `cx` and `cy` attributes are bound to this state, causing the circle to continuously reposition as the mouse moves. The SVG is rendered via React’s `ReactDOM.render`, with the circle radius fixed at 30 pixels.

Mouse follow

A moving circle follows the mouse cursor across an SVG canvas, with its position updating in real time as the pointer moves. The example uses React state management with the `useState` and `useCallback` hooks to track cursor coordinates, and renders the circle via SVG elements in a React component. Mouse move events trigger updates to the circle's center position, initialized to the middle of a 960×500 viewport. The visualization demonstrates a simple interactive pattern using React's declarative rendering and event handling.

Mouse Follower

A circle follows the mouse cursor across an SVG canvas. The example demonstrates React state management and event handling by updating the circle's center coordinates in response to mouse movement. It uses React 16.9 with hooks like `useState`, `useCallback`, and `useEffect` to track and render the cursor position as SVG elements. The project is built with the React DOM renderer and is initialized through an HTML file that loads both React and the compiled bundle.

Mouse following Circle

This example shows a single circle that follows the mouse cursor as it moves over an SVG canvas. The circle’s center coordinates are updated on every mouse movement event, re-rendering the shape in real time. Built with React, it uses the `useState` hook to manage the mouse position and an `onMouseMove` handler on the SVG element. The visualization demonstrates a straightforward interaction pattern, rendering with ReactDOM and the SVG namespace, with no data source involved.

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.

Interaction with React

A circle in an SVG canvas follows the mouse cursor, with its position updated continuously. The example demonstrates unidirectional data flow in React, where the current mouse coordinates serve as state and drive the circle's rendering. It uses React's `useState` and `useCallback` hooks to manage the mouse position and optimize event handling. The SVG element listens for mouse movement events, and the circle's `cx` and `cy` attributes are bound to the state values, rendering via ReactDOM with an inline SVG.

Mouse Follow

A circle inside an SVG follows the mouse's movement across the viewport in real time. The app initializes the circle at the center of a 960-by-500 coordinate space, then updates its position on every mousemove event. React’s `useState` and `useCallback` hooks manage the mouse coordinates, which are passed to the circle’s `cx` and `cy` attributes. The example renders using ReactDOM and React 16.13.1, with the SVG’s `onMouseMove` handler triggering the state update.
