A circle follows the mouse cursor within a full-window SVG canvas. The example demonstrates unidirectional data flow in React, where the mouse position is the data. The circle’s center coordinates are set from the current state, initialized to the window’s center. The code uses D3’s `select` API to manage the SVG and circle elements, and RDP’s `viz` and `setState` functions to handle rendering and state updates in response to `mousemove` events.

This example demonstrates a mouse follower where a circle visually tracks the cursor’s position across the viewport, serving as a minimal illustration of unidirectional data flow in a React-driven D3 visualization. The code uses D3’s `select` and `join` API to incrementally build an SVG and circle element, updating their `cx` and `cy` attributes based on mouse events. State changes trigger a re-render through the `setState` callback, with the initial position defaulting to the center of the window.

A circle follows the mouse cursor within an SVG canvas, responding to every movement by updating its center coordinates. This example uses React’s `useState` to track the pointer position and D3’s `arc` (though not directly applied), with the SVG’s `onMouseMove` event triggering a state update that repositions the circle. The visualization runs inside an HTML page that imports React and D3 via CDN, rendering through `ReactDOM.render`.

A circle follows the mouse cursor across an SVG canvas, with its position updating in real time as the pointer moves. The visualization uses React state and a `handleMouseMove` callback to track the cursor’s clientX and clientY coordinates, rendering the circle via SVG circle elements. Both React and D3 v5 are loaded from CDNs, with ReactDOM managing the component lifecycle. The circle starts at the canvas center and responds immediately to every mouse movement, demonstrating a simple interactive pattern built with the React hooks `useState` and `useCallback`.

A circle follows the mouse cursor across an SVG canvas, recentering itself as the pointer moves. The example uses React hooks `useState` and `useCallback` to manage the mouse position and update the circle’s `cx` and `cy` attributes via the SVG `onMouseMove` event. Rendering is handled by React DOM, with the visualization limited to a static circle whose radius remains constant.

A circle follows the mouse cursor across an SVG canvas, responding in real time to pointer movement. The example demonstrates React state management with a `useState` hook and `useCallback` for the mouse event handler, while ReactDOM renders the SVG circle at the updated coordinates. It uses React 16.9.0 and renders entirely via SVG elements, with the initial circle positioned at the center of a 960×500 viewport.

This example shows a simple interactive circle that tracks the mouse cursor as it moves across an SVG canvas. Built with React 16.9 and rendered through ReactDOM, it uses the `useState` and `useCallback` hooks to manage and update the circle’s coordinates in response to the SVG’s `onMouseMove` event. The circle’s position is derived directly from the browser’s `clientX` and `clientY` event properties, with no external data source—the visualization is purely a demonstration of state-driven, event-based rendering in a React component.

This example demonstrates a mouse-tracking visualization using React, where a circle follows the cursor’s position across an SVG canvas. The app initializes the circle at the center of a 960×500 viewport and updates its coordinates on every `mousemove` event. It uses React hooks (`useState` and `useCallback`) to manage and memoize the mouse position state. The rendering relies on ReactDOM and SVG elements, with no external data source, purely illustrating interactive event handling and declarative updates.

A circle follows the mouse cursor across a full-screen SVG canvas, updating its position through a unidirectional state flow. The `viz.js` module listens for `mousemove` events on the SVG and calls `setState` to store the cursor’s x and y coordinates, which are then passed back as props to re-render the circle’s `cx` and `cy` attributes. Using D3 v7’s `select` and data joins, the code binds a single circle element to the state, demonstrating a simple reactive pattern where the view is a pure function of the current state.
