A single blue circle tracks the mouse position within an SVG canvas. The visualization demonstrates how React state updates can drive SVG element positioning in real time. The code uses React's `useState` and `useCallback` hooks within a functional component to capture `clientX` and `clientY` coordinates from the SVG's `onMouseMove` event, updating the circle's `cx` and `cy` attributes. D3 v7 is loaded but only for its `arc` function, which is unused in the final rendering. The example renders purely with React and SVG, with no external data sources.

An interactive SVG visualization renders a single circle that follows the mouse cursor across a 960-by-500 canvas. The React component tracks pointer movement via the `onMouseMove` event and updates the circle’s `cx` and `cy` attributes through `useState` and `useCallback`. Initially positioned at the canvas center, the circle moves smoothly with the cursor. The example demonstrates state-driven rendering in React 17 with D3 v7, using plain SVG elements rather than data joins or scales. No external data source is involved; the visualization purely reacts to user input.

Mouse Follower

A single circle tracks the mouse cursor across an SVG canvas, moving to follow the pointer’s exact coordinates. The example uses React state management with `useState` and `useCallback` to update the circle’s `cx` and `cy` attributes on every `mousemove` event. It renders with D3’s `arc` import unused, relying instead on a plain SVG circle. The visualization demonstrates basic interaction and state-driven DOM updates within a React component.

Mouse Follower

A circle tracks the mouse's position across an SVG canvas, updating its center coordinates in real time. The React component uses the `useState` hook to store the current mouse position and `useCallback` to handle `onMouseMove` events. D3's `arc` API is imported but not used, while the circle's movement relies purely on React state updates triggered by the `clientX` and `clientY` values from the event object. The visualization demonstrates a simple interactive pattern with SVG rendering within a React application.

Mouse Follower

A circle follows the mouse cursor inside an SVG canvas, updating its position in real time as the pointer moves. The example combines React state management with D3.js v7 for SVG rendering, using the `useState` hook to track mouse coordinates and a `useCallback` event handler to update them on `mousemove`. The circle is drawn with hardcoded width and height values, and the mouse position is captured via `clientX` and `clientY` from the native browser event.

A circle follows the mouse cursor across an SVG canvas, updating its position in real time as the pointer moves. The visualization uses React state to track mouse coordinates via the `onMouseMove` event handler and renders a single `<circle>` element with D3 v7’s selection-free React integration. The SVG viewport is fixed at 960 by 500 pixels, and the circle’s center tracks the clientX and clientY values directly.

A circle follows the mouse cursor across an SVG canvas in this React-based visualization. The example uses React's `useState` and `useCallback` hooks to track `clientX` and `clientY` coordinates from a mouse move event, updating the circle's `cx` and `cy` attributes in real time. Rendered with D3 v6 for SVG elements and React 17, the circle starts centered at (480, 250) with a radius of 30 pixels. No data source is involved; the visualization demonstrates interactive event handling and state-driven positioning.

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.

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.
