A circle follows the mouse cursor across an SVG canvas. React state tracks the pointer position, updating on every `mousemove` event, and re-renders the circle's `cx` and `cy` coordinates accordingly. The example uses React 17 with hooks (`useState`, `useCallback`) and renders through `ReactDOM`. D3 v7 is loaded but not directly used. The SVG has a fixed width of 960 pixels and height of 560 pixels, with the circle initially centered at the canvas midpoint.

MouseFollower

A circle follows the mouse cursor across an SVG canvas, updating its position in real time as the pointer moves. The example uses React state with the `useState` and `useCallback` hooks to track mouse coordinates, which are passed as `cx` and `cy` attributes to a D3 v7-generated circle element. The SVG itself handles mouse movement events via `onMouseMove`, while the ReactDOM library renders the component into the DOM.

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 plain SVG circle follows the user's mouse cursor across a 960-by-500 canvas. The React component tracks `clientX` and `clientY` from a `mousemove` event handler, updating state to reposition the circle's `cx` and `cy` attributes. The example uses React's `useState` and `useCallback` hooks, with D3 v7 loaded for potential supplementary utilities, though rendering relies solely on SVG elements and React's declarative updates.

Mouse Follower

A mouse follower example renders a single SVG circle that tracks the cursor's position within a 960 by 500 viewport. Using React state hooks (`useState` and `useCallback`), the component updates the circle's `cx` and `cy` coordinates on every `mousemove` event. D3 version 7 is loaded for potential utilities, though the interaction relies solely on React's event handling and SVG rendering. The circle starts centered and moves fluidly, demonstrating simple interaction between DOM events and React's declarative UI updates.

Mouse Follower

A circle follows the mouse cursor across an SVG canvas, updating its position in real time as the pointer moves. The example uses React state to track the mouse coordinates via an `onMouseMove` event handler, which calls `setMousePosition` to re-render the circle at the new location. The SVG element defines the drawing area, and the circle’s `cx` and `cy` attributes are bound to the state values. No data is loaded; the visualization demonstrates interactive state management with React’s `useState` and `useCallback` hooks within a D3-enabled SVG environment.

Mouse Follower

A circle follows the mouse cursor across an SVG canvas, centering itself on the pointer’s coordinates. The example demonstrates React state management to track mouse movement, updating the circle’s position on every move event. It uses React’s `useState` and `useCallback` hooks alongside D3 v6 for the SVG rendering, with an initial circle centered at 480, 250. The visualization responds interactively in real time, showcasing a minimal integration of React and D3 for dynamic graphics.

Mouse Follower

A circle follows the mouse cursor inside an SVG canvas, updating its position in real time as the pointer moves. The example combines React state management with D3.js v7 for SVG rendering, using the `useState` hook to track mouse coordinates and a `useCallback` event handler to update them on `mousemove`. The circle is drawn with hardcoded width and height values, and the mouse position is captured via `clientX` and `clientY` from the native browser event.

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.
