A circle follows the mouse pointer across the screen, updating its position in real time based on cursor movement. The visualization demonstrates unidirectional data flow with D3 v7 and React, where mouse events trigger state updates that re-render the circle’s coordinates. The code uses d3-selection `select` and `join` to bind SVG elements, with an initial state centered in the viewport. The React framework manages state through a `setState` callback, while the D3 `mousemove` event handler captures pointer positions.

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 with React

A circle follows the mouse cursor across the screen, updating its position in real time. The example integrates D3.js selection and event handling within a React component, using React's `useState` and `useLayoutEffect` to manage state and trigger re-renders. The `viz.js` module binds a D3 `mousemove` event to an SVG and updates the circle's `cx` and `cy` attributes based on cursor coordinates. Initial state is set to the center of the window before any mouse movement occurs.

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 single circle follows the mouse cursor across an SVG canvas, updating its position in real time. The visualization demonstrates React’s state management and event handling, using the `useState` hook to track cursor coordinates and the `onMouseMove` event to update them. The circle’s center is bound to the `mousePosition` state, and its radius is fixed at 30 pixels. The code renders the scene with React and ReactDOM, while D3 is loaded but not explicitly used in the visible logic.

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 as it moves across an SVG canvas, creating a simple interactive pointer-tracking effect. The visualization uses React state to store the cursor's coordinates and updates the circle's position through an `onMouseMove` event handler. Rendered with D3 v7 and React 18, the SVG circle has an aquamarine fill with a green stroke. The code relies on React's `useState` and `useCallback` hooks to manage and update the mouse position efficiently.

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 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.
