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 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 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 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 across an SVG canvas in this React-based visualization. The example uses React's `useState` and `useCallback` hooks to track `clientX` and `clientY` coordinates from a mouse move event, updating the circle's `cx` and `cy` attributes in real time. Rendered with D3 v6 for SVG elements and React 17, the circle starts centered at (480, 250) with a radius of 30 pixels. No data source is involved; the visualization demonstrates interactive event handling and state-driven positioning.

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 within an SVG canvas, updating its center position in real time. The visualization uses React's `useState` and `useCallback` to manage mouse-move events, while the SVG `onMouseMove` handler captures pointer coordinates. The circle’s `cx` and `cy` attributes are bound to the state, and the scene is rendered via `ReactDOM.render` with a D3.js library import for potential data handling.

Mouse follower

This example demonstrates a mouse-follower visualization: a circle that tracks the cursor’s position across an SVG canvas. The circle moves continuously as the user moves the mouse, with its center coordinates updated from the event’s `clientX` and `clientY` values. The implementation uses React’s `useState` and `useCallback` hooks to manage and update the mouse position, while the `<svg>` element’s `onMouseMove` handler triggers the state change. The rendering is done via SVG, with a single `<circle>` element whose `cx` and `cy` attributes are bound to the current position. D3 is loaded but not used for interaction or data processing.
