A single black circle follows the mouse cursor across an SVG canvas. The example demonstrates how React manages dynamic state alongside D3’s rendering environment. Using React’s `useState` and `useCallback` hooks, the component tracks mouse coordinates from the SVG’s `onMouseMove` event and updates the circle’s `cx` and `cy` attributes. The circle is rendered via React’s JSX, while D3 v5 is loaded but not directly used for interaction; the visualization relies entirely on React’s state updates to redraw the SVG element in real time.

Mouse Follower

A black circle follows the mouse as it moves across a blank SVG canvas. The example demonstrates React state management with the `useState` and `useCallback` hooks to track cursor coordinates. Each mouse movement updates the circle’s `cx` and `cy` attributes, while d3.v5 is loaded but not used in the visible logic. The SVG rendering is handled by React, with the circle’s position initialized at the canvas center.

This example displays a single black circle that follows the mouse cursor across an SVG canvas. The circle’s position updates live based on the cursor’s coordinates, which are tracked through React state. The code uses React’s `useState` and `useCallback` hooks, an SVG `<circle>` element, and D3.js version 5 for the underlying library. The rendering relies on ReactDOM to mount the component, with no additional data sources or animations beyond the direct mouse-following interaction.

Mouse Follower

A black circle follows the mouse pointer across a blank SVG canvas. The example demonstrates interactive state management in React, where mouse coordinates update the circle’s position in real time. It uses React’s `useState` and `useCallback` hooks to track and handle mouse movement events, while d3.v5 provides the SVG rendering utilities. The circle’s center is set directly from the `clientX` and `clientY` properties of the browser’s mouse event, with no additional data or animation logic.

Mouse Follower

A single black circle follows the mouse cursor across a blank SVG canvas. The circle’s position updates in response to mouse movement via a React state hook (`useState`) and an `onMouseMove` event handler. The example uses React 16.9 for component rendering and event handling, with the SVG element created directly in JSX. No external data or D3 functions are used; only React’s state management drives the dynamic repositioning.

A single dark circle follows the mouse cursor across an SVG canvas in a React-based visualization. The circle’s position updates live via React’s `useState` hook, driven by the SVG `onMouseMove` event, which captures the cursor’s client coordinates. Rendering uses plain SVG elements, with D3 v5 loaded but not actively used in the logic. The example demonstrates reactive state-driven updates in React for interactive graphics, with the circle centered on the pointer’s exact location.

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 circle follows the mouse cursor as it moves across an SVG canvas. The React component tracks pointer coordinates via the `onMouseMove` event and updates the circle’s `cx` and `cy` attributes through `useState` and `useCallback`. Rendered with D3 v5’s SVG helpers within React 16.9, the example demonstrates real-time state-driven positioning without external data.

A single black circle follows the mouse cursor across an SVG canvas. The circle’s position updates on every `mousemove` event, driven by React state. The application uses React’s `useState` and `useCallback` hooks to track the cursor’s coordinates and re-render the circle accordingly. The example is rendered with D3.js v6 for SVG creation, while React handles the interactive state, with no external data source.
