This example shows a single circle following the mouse as it moves across an SVG canvas. The circle’s position updates continuously based on the cursor’s client coordinates, shifting smoothly across a 960×500 viewport. The visualization uses React’s `useState` and `useCallback` hooks to manage and update the mouse position, while `ReactDOM.render` mounts the component into the DOM. The SVG `<circle>` element is rendered directly, with its `cx` and `cy` attributes bound to the current mouse coordinates.

This example demonstrates a React component that renders a single circle that follows the mouse cursor across an SVG canvas. Using React’s `useState` hook, the component tracks the cursor’s `clientX` and `clientY` coordinates through an `onMouseMove` event handler, updating the circle’s `cx` and `cy` attributes in real time. The visualization is built with React 16 and ReactDOM, rendering directly into a 960×500 SVG viewport. It shows how declarative state management and SVG’s vector graphics can create a simple interactive pointer-tracking effect without any external data or charting libraries.

A circle follows the mouse cursor inside an SVG canvas, with its position updating in real time. The example demonstrates React state management, using the `useState` hook to store mouse coordinates and `useCallback` to handle mouse movement events. The circle’s center is set to the tracked `clientX` and `clientY` values, and it is rendered with a fixed radius of 30 pixels within a 960 by 500 viewport. The SVG element captures the `onMouseMove` event, and no external data is loaded.

This example demonstrates a React component that renders an interactive SVG circle. The circle follows the mouse cursor across a 960-by-500 viewport, updating its position in real time through React state management. The code uses React hooks (`useState`, `useCallback`) to track mouse coordinates and re-render the circle on every `onMouseMove` event. The SVG circle is rendered with a fixed radius of 30 pixels, and the initial mouse position is set to the center of the viewport. The project relies on React 16.13.1 and ReactDOM for rendering the component into the DOM.

The visualization is an interactive React application that renders a single SVG circle, which follows the cursor's movement across the viewport. The circle's position updates in real time based on the mouse coordinates captured by the `onMouseMove` event handler. Using React's `useState` hook, the component tracks the mouse position and re-renders the SVG element with the new `cx` and `cy` attributes. The code employs the React and ReactDOM libraries, rendering the visualization directly into the HTML root element. The SVG canvas is 960 by 500 pixels, with the circle's default starting position at the center.

Fork of Mouse follower

This React and SVG example displays a single circle that follows the mouse cursor across a 960 by 500 canvas. The circle’s position updates in response to mouse movement events, initially centered on the screen. The application uses React’s `useState` and `useCallback` hooks to manage the cursor coordinates, and ReactDOM renders the SVG element with an `onMouseMove` handler. The visualization demonstrates real-time interaction by directly mapping the cursor’s client coordinates to the circle’s `cx` and `cy` attributes.

This example demonstrates a mouse follower visualization where a circle tracks the cursor’s position across an SVG canvas. The React app uses the `useState` hook to store mouse coordinates, updating them on every `onMouseMove` event. The circle radius is fixed at 50, and it renders via ReactDOM into an HTML root element. The visualization highlights real-time interaction, with the SVG’s width and height set to 960 by 500 pixels. It relies on React 18.2.0 and ReactDOM for rendering, showing how state management and event handling create a responsive graphical effect.

This example demonstrates a circle following the mouse cursor inside an SVG canvas using React’s `useState` hook to track position changes. The visualization updates the circle’s `cx` and `cy` attributes in response to the `onMouseMove` event, rendering with ReactDOM and D3.js v5 as a dependency. The code relies on clientX and clientY coordinates from the event object to reposition the circle dynamically, with the initial state centered at half the SVG’s width and height.

A React component renders an SVG circle that follows the mouse cursor across a 960x500 viewport. The application uses React's `useState` hook to track the cursor's `clientX` and `clientY` coordinates, updated by an `onMouseMove` event handler on the SVG element. The circle's `cx` and `cy` attributes bind to the stored position, creating a direct visual response to pointer movement. The visualization demonstrates a simple, interactive SVG rendering approach using React 18 and ReactDOM.
