A React component uses SVG to render a single circle that tracks the mouse cursor across a 960-by-500 viewport. The `useState` hook stores the cursor’s x and y coordinates, initialized at the center, while the `useCallback` hook wraps the `handleMouseMove` event handler to update that state on every mouse movement. The circle’s `cx` and `cy` attributes are bound to the stored coordinates, and the SVG element’s `onMouseMove` prop triggers the update. This example demonstrates interactive state management and event handling within a React-driven SVG visualization.

React Draw with Mouse

A React component renders an SVG circle that follows the mouse pointer across a 960×500 canvas. The SVG’s `onMouseMove` event updates React state via `useState`, and `useCallback` memoizes the handler to prevent unnecessary re-renders. The circle’s `cx` and `cy` coordinates are bound to the current mouse position, demonstrating a reactive, declarative drawing interaction. Unlike D3, this example relies solely on React’s state management and SVG’s native event handling to create a live, mouse-driven visualization.

Mouse Move React

A React SVG visualization tracks the mouse position within a 960 by 500 viewport. It renders a single circle that follows the cursor, using React’s `useState` to store coordinates and `useCallback` to optimize the mouse-move handler. The circle’s center updates directly from the event’s `clientX` and `clientY` values, demonstrating a minimal interactive component built with React 16 and rendered through `ReactDOM.render`.

Mouse event

A React and SVG visualization demonstrates mouse tracking by rendering a single circle that follows the cursor. The circle's position updates dynamically via React's `useState` hook, which stores the mouse coordinates from the `onMouseMove` event handler. The initial position is set to the center of a 960x500 SVG canvas, and the circle has a radius of 30 pixels. The code uses ReactDOM to render the component to the DOM, with the SVG's width and height explicitly defined.

circle and mouse

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 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 Events

A React application demonstrates mouse event handling by rendering a single SVG circle that follows the cursor across the viewport. The circle's position updates in real time through the `onMouseMove` event, which captures `clientX` and `clientY` coordinates and stores them in state via the `useState` hook. The `useCallback` hook optimizes the event handler. The visualization uses React 16.9 and renders directly to SVG, with the window dimensions determining the drawing area.

follow the mouse

A React SVG renders a single black circle that follows the mouse cursor across the full browser window. The component tracks pointer position via the `onMouseMove` event, storing coordinates in state with `useState` and updating them through `useCallback`. The circle's `cx` and `cy` attributes are bound to the current mouse coordinates, redrawing on every move. This example demonstrates real-time interaction between user input and SVG elements using React's declarative rendering.

Mouse Interaction with React

A circle rendered as an SVG element follows the mouse cursor within a fixed 900×500 viewport. The React component `App` tracks pointer coordinates via an `onMouseMove` handler, updating the circle's `cx` and `cy` attributes through state managed by `useState`. The initial position is centered at half the width and height. React 16.13.1 and ReactDOM render the interactive graphic, which updates smoothly as the user moves the mouse over the SVG area.
