An interactive SVG circle follows the mouse cursor across a 960x500 canvas. The React application tracks pointer movement via the `onMouseMove` event handler, updating the circle's center coordinates with each `clientX` and `clientY` value. Using `useState` for position state and `useCallback` to optimize the event handler, the code renders a single red circle (radius 30) whose position updates in real time. The example demonstrates a basic React-D3 integration, with the visualization rendered entirely through React's declarative SVG output.

Mouse Follower

An interactive SVG visualization renders a single circle that follows the mouse cursor across a 960-by-500 canvas. The React component tracks pointer movement via the `onMouseMove` event and updates the circle’s `cx` and `cy` attributes through `useState` and `useCallback`. Initially positioned at the canvas center, the circle moves smoothly with the cursor. The example demonstrates state-driven rendering in React 17 with D3 v7, using plain SVG elements rather than data joins or scales. No external data source is involved; the visualization purely reacts to user input.

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.

A circle follows the mouse cursor across an SVG canvas in this React-based visualization. The app tracks pointer coordinates using a React `onMouseMove` event handler and stores them in component state with the `useState` hook. Each mouse movement updates the circle’s `cx` and `cy` attributes, repositioning it instantly at the cursor’s location. The visualization uses React 16.9 and D3 v5 for rendering, with the SVG circle set to a fixed radius of 30 pixels. No data source is involved; the interaction is purely driven by user input.

A circle follows the mouse cursor across an SVG canvas, creating a simple interactive visual response. The React application tracks cursor position through an `onMouseMove` event handler, updating state via the `useState` and `useCallback` hooks, and renders the circle using D3 v7 within an SVG element. The circle’s center coordinates are dynamically bound to the latest mouse position, with a fixed radius of 30 pixels.

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 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.

A circle tracks the mouse cursor across a 960 by 500 SVG canvas, updating its position in real time as the user moves the pointer. The React component uses `useState` to store the mouse coordinates and `useCallback` to handle the `onMouseMove` event, passing the event's `clientX` and `clientY` values to reposition the circle via its `cx` and `cy` attributes. It renders with React 17 and D3 v7.
