A circle follows the mouse cursor across an SVG canvas. The example uses React with a `useState` hook to track the mouse position, updating the circle's `cx` and `cy` attributes during `onMouseMove` events. It renders a single red circle with a radius of 30 pixels inside an SVG viewport sized 960 by 500 pixels, using D3.js version 7 and React 18.

Mouse Follower

A circle follows the mouse cursor across a full-screen SVG canvas. The circle's position is bound to the mouse coordinates, updated on every mouse move event. The example uses React with a `useState` hook to manage the cursor position, and the ReactDOM `render` method to mount the component. D3.js is loaded but not actively used in the rendering logic, which relies solely on native SVG elements and React event handling. The circle is drawn with a fixed radius of 30 pixels.

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

An interactive SVG circle follows the mouse cursor across a 960x500 canvas. The React application tracks pointer movement via the `onMouseMove` event handler, updating the circle's center coordinates with each `clientX` and `clientY` value. Using `useState` for position state and `useCallback` to optimize the event handler, the code renders a single red circle (radius 30) whose position updates in real time. The example demonstrates a basic React-D3 integration, with the visualization rendered entirely through React's declarative SVG output.

Mouse Follower

A circle follows the mouse cursor across an SVG canvas. The example demonstrates React state management with D3.js in the background, using React `useState` and `useCallback` to track cursor coordinates via the `onMouseMove` event. The circle’s position updates in real time through React’s re-rendering, with its `cx` and `cy` attributes bound to the current mouse position. It renders a single circle with a radius of 30 pixels on a 960 by 500 viewport.

Mouse Follower

A circle follows the mouse cursor as it moves across an SVG canvas. The React component tracks pointer coordinates via the `onMouseMove` event and updates the circle’s `cx` and `cy` attributes through `useState` and `useCallback`. Rendered with D3 v5’s SVG helpers within React 16.9, the example demonstrates real-time state-driven positioning without external data.

Mouse Follower

A circle with a radius of 30 pixels follows the mouse cursor across an SVG canvas. The React application tracks pointer coordinates via the `onMouseMove` event handler, updating the circle's `cx` and `cy` attributes through `useState`. The visualization demonstrates reactive rendering with React 17 and SVG, using the `useCallback` hook to manage the event listener. The initial mouse position is centered at (480, 250) on a 960-by-500 canvas.

Mouse follower

A circle follows the mouse cursor across an SVG canvas, creating a simple interactive visual response. The React application tracks cursor position through an `onMouseMove` event handler, updating state via the `useState` and `useCallback` hooks, and renders the circle using D3 v7 within an SVG element. The circle’s center coordinates are dynamically bound to the latest mouse position, with a fixed radius of 30 pixels.

Mouse Follower

A circle follows the mouse cursor within an SVG canvas, with its center position updating live to match the pointer's coordinates. The visualization uses React's `useState` and `useCallback` hooks to manage cursor tracking, while `ReactDOM` renders the SVG element and its circle to the page. The SVG's `onMouseMove` event handler captures the cursor position, and the circle's `cx` and `cy` attributes are updated accordingly with a fixed radius of 30 pixels.
