A small yellow circle follows the mouse cursor across an SVG canvas. The circle’s position is driven by React state, updated via a `useCallback` handler on the SVG’s `onMouseMove` event, which reads the native event’s `clientX` and `clientY` coordinates. The visualization is rendered using React and D3.js, with a fixed 960×500 viewport and no external dataset.

Mouse Follower

A yellow circle follows the cursor across an SVG canvas, updating its center position in real time as the mouse moves. The visualization uses React's state management with an `onMouseMove` event handler to track client coordinates, while D3.js provides the SVG rendering environment. The circle's position is bound to the mouse coordinates via React's `useState` and `useCallback`, creating a direct one-to-one mapping between input and visual output.

Mouse Follower

A yellow circle follows the mouse cursor across a blank SVG canvas. The visualization directly maps the cursor's client coordinates to the circle's center position, creating an immediate and direct interactive response. Built with React, the application uses the `useState` and `useCallback` hooks to manage and update the mouse position state, while the SVG `onMouseMove` event triggers the state changes. The circle is rendered as an SVG element with a fixed radius, and the code initializes the circle at the center of a 960 by 500 viewport.

Mouse Follower

A yellow circle follows the mouse cursor as it moves across an SVG canvas. The visualization uses React state management with the `useState` and `useCallback` hooks to track the cursor's `clientX` and `clientY` coordinates, updating the circle's `cx` and `cy` attributes via React's render cycle. The SVG is rendered by ReactDOM, while D3 v5 is loaded but not directly used in this example. The circle maintains a fixed radius of 30 pixels and responds immediately to pointer movement within the 960×500 viewport.

Mouse Follower

A yellow circle follows the mouse cursor across an SVG canvas. The visualization tracks pointer movement and repositions the circle to match the cursor’s coordinates in real time. Built with React, it uses the `useState` hook to store the mouse position and an `onMouseMove` event handler on the SVG element to update that state. The circle renders via ReactDOM with SVG markup, and its `cx` and `cy` attributes are bound to the current mouse coordinates.

Mouse Follower

A yellow circle follows the mouse cursor across an SVG canvas, updating its position in real time as the pointer moves. Built with React and D3 v7, the visualization uses a stateful `mousePosition` variable updated via an `onMouseMove` event handler on an SVG element, rendering the circle with D3's SVG primitives.

Mouse Follower

A yellow circle follows the mouse cursor across a full-screen SVG canvas. The visualization demonstrates a simple interactive state update in React, where the circle’s position mirrors the cursor’s coordinates in real time. The component uses React’s `useState` hook to track the mouse position and `useCallback` to handle the `onMouseMove` event, updating the circle’s `cx` and `cy` attributes. The SVG rendering is driven entirely by React’s declarative updates, with no additional data source or animation library involved.

Mouse Follower

A yellow circle follows the mouse cursor's movement within an interactive SVG canvas. The visualization uses React's `useState` and `useCallback` hooks to track the mouse position, updating the circle's `cx` and `cy` attributes on every movement event. The code integrates React and D3.js version 5, rendering the circle as an SVG element within a React component. The coordinate system is initialized to the center of a 960 by 500 pixel canvas, and the circle is drawn with a fixed radius of 30 pixels.

Mouse Follower

A yellow circle follows the mouse as it moves across a blank SVG canvas. The visualization tracks the cursor position in real time, rendering the circle at the exact coordinates of the pointer. Built with React and ReactDOM, it uses SVG’s `onMouseMove` event handler to capture the cursor’s client coordinates and update the circle’s `cx` and `cy` attributes. The circle maintains a constant radius of 30 pixels within a 960 by 500 viewport.
