A circle follows the mouse cursor across an SVG canvas, updating its position in real time. The example uses React's `useState` and `useCallback` hooks to track mouse coordinates via an `onMouseMove` event handler, then renders a single circle element with those coordinates as its `cx` and `cy` attributes. The SVG has a fixed width of 960 and height of 500 pixels, with the circle initially centered at the midpoint.

This example shows a simple interactive visualization where a gray circle follows the mouse cursor across an SVG canvas. The circle starts at the center of a 960 by 500 pixel viewport and repositions instantly whenever the pointer moves. The code uses React's `useState` and `useCallback` hooks to track mouse coordinates via the SVG `onMouseMove` event, updating the circle’s `cx` and `cy` attributes through ReactDOM rendering. It demonstrates basic state-driven SVG updates in a React application.

This example demonstrates a simple interactive visualization inside an SVG canvas: a circle continuously follows the mouse cursor across the screen. It serves as a basic demonstration of handling mouse events and updating React state in response to user input. Built with React and ReactDOM, the application uses the `useState` hook to track the cursor's `clientX` and `clientY` coordinates, updating them via the `handleMouseMove` callback attached to the SVG element's `onMouseMove` event. The rendered SVG circle’s `cx` and `cy` attributes are bound directly to the mouse position state, causing the circle to track the pointer in real time.

A React component renders an SVG circle that follows the mouse cursor across a 960 by 500 pixel canvas. The circle starts at the center and updates its position on every `mousemove` event via React's `useState` and `useCallback` hooks. The `handleMouseMove` callback reads the event's `clientX` and `clientY` coordinates to set the new circle center, using ReactDOM to mount the app. No data source is involved; the visualization simply tracks pointer movement in real time.

This interactive visualization renders a blank SVG canvas where a single circle follows the mouse cursor. Implemented with React and ReactDOM, the program updates the circle's cx and cy coordinates based on pointer movement. The SVG viewport is set to 960 by 500 pixels, and the circle has a fixed radius of 30 pixels, creating a simple but responsive pointer-tracking effect.

This interactive visualization displays a single circle that follows the mouse cursor across an SVG canvas. Built with React, the example uses the `useState` hook to track the cursor's `clientX` and `clientY` coordinates within an `onMouseMove` event handler on the `<svg>` element. The circle's center position updates reactively via `setMousePosition`, rendering in real time as the user moves the mouse. The visualization demonstrates a simple, responsive interaction pattern using React's declarative state management and SVG rendering.

This example displays a static SVG circle at the center of the viewport, with mouse movement tracked and logged to the console. Built with React and D3, the circle is rendered via JSX inside an SVG element whose onMouseMove handler captures the cursor position. The React event handler logs clientX and clientY coordinates, demonstrating basic event binding and state management without animating the circle itself.

The visualization displays a single circle at the center of an SVG canvas. As the mouse moves over the canvas, the browser logs the cursor’s X and Y coordinates to the console using the `onMouseMove` event handler. Built with React and rendered as an SVG element, the circle’s static position is defined by `circleX` and `circleY` constants. The example demonstrates basic event handling and coordinate tracking without any dynamic visual response.
