Mouse Follower

A black circle follows the mouse cursor across an SVG canvas, updating its position in real time with each mouse movement. The visualization uses React's `useState` and `useCallback` hooks to manage the circle's coordinates, while ReactDOM renders the SVG element. Mouse events are captured through the SVG's `onMouseMove` handler, which updates the circle's `cx` and `cy` attributes. The code imports React, ReactDOM, and D3 v5, though D3 is not utilized in the interaction logic itself.

A red circle follows the mouse cursor across an SVG canvas, with its position updating in real time. Built with React and D3 v7, the visualization uses React's `useState` and `useCallback` hooks to track mouse coordinates on a dedicated SVG `onMouseMove` event handler. ReactDOM renders the SVG, and the circle's `cx` and `cy` attributes update live as the pointer moves.

Mouse Follower

A red circle follows the mouse cursor across an SVG canvas, updating its position in real time as the user moves. Built with React and D3 v5, the app uses React’s `useState` and `useCallback` hooks to track mouse coordinates via the SVG `onMouseMove` event, then re-renders the circle’s `cx` and `cy` attributes accordingly. No data source is involved; the visualization simply demonstrates interactive event handling and state-driven rendering with SVG.

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 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. The visualization demonstrates React's state management with D3's event handling, using a `useState` hook to track cursor coordinates and a `useCallback` hook to efficiently update the circle's `cx` and `cy` attributes on every mouse move. The D3 v5 library renders the SVG element.

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.
