A circle follows the mouse cursor across a full-screen SVG canvas, updating its position in real time. The visualization uses React state to track the cursor's clientX and clientY coordinates, triggered by an onMouseMove event handler on the SVG element. Built with React 16.9 and D3 v7, the circle is rendered directly as an SVG `<circle>` element, with its cx and cy attributes bound to the current mouse position. No data source is involved; the interaction is purely event-driven.

A program that follows your mouse with a circle.

A circle follows the mouse cursor across an SVG canvas, with its position updating in real time as the pointer moves. The code uses React's `useState` hook to track the cursor's client coordinates and re-renders the circle's `cx` and `cy` attributes accordingly. The example imports `range` from d3.v7 and builds an SVG element with a mouse-move event handler that captures the cursor's position. No data visualization occurs; the interaction is purely a demonstration of event handling and state-driven SVG rendering in a React environment.

A program that follows your mouse with a circle

A circle follows the mouse cursor across an SVG canvas. The visualization uses React state to track the cursor's pixel coordinates and updates the circle's center position on every mouse move. The code imports the `arc` function from d3 but does not use it; rendering is handled entirely through React's declarative SVG elements. The example demonstrates a simple interactive pattern using React's `useState` and `useCallback` hooks within a D3-styled viewport.

Mouse follower

A circle drawn with SVG follows the mouse cursor across a 960 by 500 pixel canvas. The visualization tracks the pointer's absolute client coordinates on every mouse movement event, updating the circle's center position accordingly. Built with React, the example uses the `useState` hook to store the current mouse position and a `useCallback` handler to update it, while the circle itself is rendered as an SVG `<circle>` element. The code relies on React 18 and D3 v7 only for DOM rendering, with no data or additional D3 visualization APIs involved.

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 across an SVG canvas, updating its position in real time as the pointer moves. The visualization uses React state to track mouse coordinates via the `onMouseMove` event handler and renders a single `<circle>` element with D3 v7’s selection-free React integration. The SVG viewport is fixed at 960 by 500 pixels, and the circle’s center tracks the clientX and clientY values directly.

Mouse Follower

A circle follows the mouse cursor across a 960 by 500 pixel SVG canvas, updating its position in real time as the pointer moves. The visualization is built with React (using the `useState` hook) and renders the circle via an SVG `<circle>` element. Mouse movement is captured through the SVG's `onMouseMove` event handler, which updates the circle's `cx` and `cy` coordinates. The example uses D3.js v7 and ReactDOM to render directly into the page's root element, with no external data source.

A circle follows the mouse cursor within an SVG canvas, updating its position in real time as the pointer moves. Built with React, the application tracks mouse coordinates using an `onMouseMove` event handler and stores them in state via `useState`. The circle’s `cx` and `cy` attributes are bound to this state, and the SVG is rendered through ReactDOM. D3.js is included but not used for drawing; the interaction relies solely on React’s event system.

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.
