A single black circle follows the mouse cursor across an SVG canvas, with its position updating reactively in real time. The circle’s center is driven by the `clientX` and `clientY` coordinates from the SVG element’s `onMouseMove` event, stored in React state via `useState` and `useCallback`. The visualization uses React 17 for rendering, D3 v7 for SVG utilities, and demonstrates a simple interactive pattern without any data source or external dataset. The circle radius is fixed at 30 pixels, and the SVG viewport is 960 by 500 pixels.

Mouse

A black circle follows the mouse cursor across an SVG canvas, updating its position in real time. The example demonstrates React's `useState` and `useCallback` hooks to manage and update the circle's coordinates based on `mousemove` events, while D3.js v7 is loaded but not directly used. The visualization shows a minimal interactive pattern, where the circle moves fluidly with cursor movement and renders via React's declarative JSX syntax.

mouse movement

A single black circle tracks the user's mouse position across an SVG canvas, creating a simple interactive visualization. The application is built with React and D3 v7, using React's `useState` hook to store and update the mouse coordinates on every `mousemove` event. The circle's center (`cx` and `cy`) is bound directly to the state, and its radius is fixed at 30 pixels. The rendering is handled entirely through React's declarative SVG elements, with no D3 components used beyond the library's inclusion in the script tags.

A black circle follows the mouse cursor across an SVG canvas, serving as a playful interactive pointer. The example is built with React and D3 v7, using React state to track mouse coordinates via an `onMouseMove` event handler. The `useState` hook stores the current `clientX` and `clientY` positions, and a `<circle>` element updates its `cx` and `cy` attributes accordingly. The SVG's width and height are fixed, and the circle has a constant radius of 30 pixels.

mouse

A black circle follows the mouse cursor across a yellow canvas, with its position updating in real time based on the pointer's coordinates. The visualization demonstrates React state management through the `useState` and `useCallback` hooks, where mouse movement events trigger position updates. The SVG circle, defined with an initial radius of 30, is rendered using ReactDOM within an SVG container sized 960 by 500 pixels. The code leverages React 16.10.0 and D3 v5, with the circle's `cx` and `cy` attributes bound directly to the tracked mouse position.

mouse follower

A single black circle on an SVG canvas tracks the user's mouse cursor in real time, creating a simple interactive visual. The example demonstrates state management in React, using the `useState` and `useCallback` hooks to update the circle's `cx` and `cy` attributes on every `mousemove` event. Rendered with SVG elements, the circle is positioned via React's `onMouseMove` handler, while D3 v5 and React 16 are loaded externally. No data source is involved; the visualization purely reacts to pointer movement within the 960 by 500 pixel viewport.

Mouse follower

A circle follows the mouse cursor across an SVG canvas, creating a simple interactive visual response. The React application tracks cursor position through an `onMouseMove` event handler, updating state via the `useState` and `useCallback` hooks, and renders the circle using D3 v7 within an SVG element. The circle’s center coordinates are dynamically bound to the latest mouse position, with a fixed radius of 30 pixels.

A black circle follows the mouse cursor across a blank SVG canvas, centering itself on the pointer's exact coordinates. The visualization demonstrates a simple interactive loop using React's `useState` and `useCallback` hooks to track `clientX` and `clientY` positions from a mouse move event, while D3 v6 handles SVG rendering. The circle has a fixed radius of 30 pixels and starts at the canvas center before responding to user movement.

Mouse Follower

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.
