A React-controlled SVG circle follows the user's mouse position across a 960×500 canvas, updating its coordinates on every `mousemove` event via the `useState` and `useCallback` hooks. The code imports `arc` from D3 v5 but does not use it, relying instead on React's synthetic event handling and direct SVG attribute updates. The circle’s center is bound to `mousePosition`, with an initial default at the canvas midpoint, and the page hides browser scrolling for a focused interactive demonstration.

Mouse follower

A React application renders an SVG circle that tracks the mouse cursor in real time. The circle's position updates via React's `useState` and `useCallback` hooks, which handle `mousemove` events on the SVG element. The example demonstrates simple interactive rendering with D3's `arc` import unused, relying instead on React's declarative state management. The visualization uses a 960x500 SVG canvas with a fixed circle radius, showing how React can manage dynamic visual updates without explicit D3 selection or transition APIs.

Mouse follower

A circle follows the mouse cursor across an SVG canvas, updating its position in real time. The example demonstrates React state management with a `useState` hook and the `onMouseMove` event handler, which captures the cursor's client coordinates and passes them to the circle's `cx` and `cy` attributes. React re-renders the SVG element on each mouse movement, while D3's `arc` import is present but unused, and no external data source is involved.

Mouse follower

A single circle follows the mouse cursor across an SVG canvas, responding in real time to pointer movement. The example demonstrates integrating D3.js with React hooks, using React's `useState` to track mouse coordinates and `useCallback` to handle the `mousemove` event. D3's `arc` API is imported but not used in the visible logic. The circle's position updates directly from the browser's `clientX` and `clientY` values, rendered as a simple SVG `<circle>` element without animation or data binding.

Mouse Follower

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 manage mouse coordinates, with the `onMouseMove` event handler updating the circle's center. D3's `arc` module is imported but not used, while the SVG `<circle>` element is rendered directly through ReactDOM. The visualization demonstrates a simple interactive pattern without any data source or animation logic beyond direct mouse tracking.

Mouse Follower

A React component renders an SVG circle at the center of a 960×500 canvas. A mouse-move event handler logs the cursor’s client coordinates to the console, but the circle itself remains stationary. The example uses React’s `onMouseMove` prop and D3’s `arc` import, though D3 is not applied to the visualization. The SVG dimensions and circle properties are defined as constants, with no data source or interactive updating of the circle’s position.

Mouse Follower

A single black circle follows the mouse as it moves across an SVG canvas. The React component tracks pointer coordinates through an `onMouseMove` event handler and updates the circle’s `cx` and `cy` attributes via React state. The example imports the `arc` function from d3 but does not use it, relying instead on plain SVG rendering and React’s `useState` and `useCallback` hooks for interactivity.

Mouse follower

A React application renders a single circle inside an SVG that follows the mouse cursor across the viewport. The component tracks pointer coordinates using a `useState` hook and updates the circle's `cx` and `cy` attributes on every `mousemove` event via a `useCallback` handler. Rendering relies on React 16.9 for state management and SVG creation, with D3 v5 loaded but not actively used for this behavior. The circle starts centered at 480 by 250 pixels and moves smoothly in response to user input.

Mouse Follower

A red circle follows the mouse cursor across an SVG canvas. The visualization updates the circle’s position in real time using React state and event handling, triggered by `onMouseMove`. It renders with SVG elements in a React component, using the `useState` and `useCallback` hooks to manage position updates. The code imports the `arc` function from d3, though the current implementation only uses a basic circle element.
