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.

Mouse Follower

A circle follows the mouse cursor within an SVG canvas, updating its position in real time to mirror the pointer's movement. The visualization demonstrates state management and event handling in a React application, where the mouse position is tracked via the SVG's `onMouseMove` event and stored in React state. The circle is rendered as an SVG `<circle>` element, with its `cx` and `cy` attributes bound to the current mouse coordinates. The code uses React Hooks, specifically `useState` and `useCallback`, alongside D3 v5 for SVG creation, all within a React 16.9 framework.

Mouse Follower

A circle follows the mouse cursor across an SVG canvas, updating its position in real time to mirror the user’s pointer movements. The visualization uses React’s `useState` and `useCallback` hooks to manage the cursor’s coordinates, captured through the `onMouseMove` event on the `<svg>` element. The circle is rendered via ReactDOM, with its center tied to the `clientX` and `clientY` values from the event, demonstrating a straightforward state-driven interactive graphic.

Mouse Follower

A circle follows the mouse cursor across an SVG canvas, updating its position in real time to mirror the pointer’s location. The visualization demonstrates React’s `useState` and `useCallback` hooks to manage mouse coordinates and re-render the circle on every move event. Built with React 16.9 and rendered as SVG, the component listens for `onMouseMove` on the `<svg>` element, extracting `clientX` and `clientY` to set the circle’s `cx` and `cy` attributes. The example uses no external data source, relying solely on user interaction.

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 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 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.

A circle follows the mouse cursor across an SVG canvas, with its position updating in real time to mirror the pointer’s coordinates. The example uses React state and a `useCallback` event handler to capture mouse movements and re-render the circle’s `cx` and `cy` attributes. Rendered as an SVG element via ReactDOM, the visualization demonstrates a simple interactive binding between user input and graphical output, leveraging D3 v5 only for the underlying scripting environment.
