A circle follows the cursor across an SVG canvas, updating its position in real time as the mouse moves. Built with React and D3 v7, the visualization uses React's `useState` hook to store the mouse coordinates and a `useCallback` handler to update them on every `onMouseMove` event. The circle is rendered as an SVG `<circle>` element, with its `cx` and `cy` attributes bound directly to the current mouse position, creating a smooth, direct response to user input.

Mouse Follower

A circle follows the mouse cursor across an SVG canvas, updating its position in real time. The visualization is built with React and D3 v6, using React's `useState` and `useCallback` hooks to track and update the mouse coordinates from the `onMouseMove` event. The circle is rendered as an SVG element with a fixed radius, and its `cx` and `cy` attributes are bound to the current mouse position. The example demonstrates a simple interactive pattern in a React-D3 integration.

Mouse Follower

A circle follows the mouse cursor across a 960-by-500 SVG canvas, updating its center position in real time. Built with React using the `useState` and `useCallback` hooks, the app listens for `onMouseMove` events on the SVG element and passes the cursor's `clientX`/`clientY` coordinates to the circle's `cx` and `cy` attributes. The visualization uses D3.js version 5 primarily for the SVG rendering within a React framework, with no external data source.

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 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.

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.

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

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.

Mouse Follower

A circle follows the mouse cursor across an SVG canvas, updating its position in real time to mirror the pointer’s movement. The visualization uses React’s `useState` and `useCallback` hooks to track cursor coordinates (`clientX`, `clientY`) and re-render the circle’s `cx` and `cy` attributes on every mouse move. The SVG element handles the `onMouseMove` event, while the circle’s radius is fixed at 30 pixels. The code imports React, ReactDOM, and D3 v5, though no D3-specific functions are invoked beyond the library’s inclusion.
