This example shows a React application that renders a single SVG circle that follows the user's mouse cursor across the full browser viewport. The circle updates its position in real time using React's `useState` hook and an `onMouseMove` event handler that reads the cursor's client coordinates. The rendering relies on `ReactDOM.render` to mount the component to the HTML root element, while D3 v5 is loaded but not utilized in the visible interaction. The SVG viewport dimensions are set dynamically from `window.innerWidth` and `window.innerHeight`.

Circle Follower

A 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 app uses React’s `useState` and `useCallback` hooks to track and update the mouse coordinates on every `onMouseMove` event, rendering a single `<circle>` element with a radius of 30 pixels. The example relies on SVG rendering within a 960×500 viewport, with the initial circle centered at the midpoint of the canvas.

Mouse Follower

A mouse follower example renders a single SVG circle that tracks the cursor's position within a 960 by 500 viewport. Using React state hooks (`useState` and `useCallback`), the component updates the circle's `cx` and `cy` coordinates on every `mousemove` event. D3 version 7 is loaded for potential utilities, though the interaction relies solely on React's event handling and SVG rendering. The circle starts centered and moves fluidly, demonstrating simple interaction between DOM events and React's declarative UI updates.

Mouse Follower(second phase)

This example renders an SVG circle that follows the mouse cursor across a 960 by 500 pixel viewport. The React component tracks pointer coordinates through an `onMouseMove` handler, storing them in state via `useState` and `useCallback`. The circle’s `cx` and `cy` attributes update reactively with each mouse movement, using React’s virtual DOM to re-render the SVG. The code imports React, ReactDOM, and D3 v7, though the interaction relies entirely on React’s event system and state management rather than D3-specific APIs.

Fork of Follower 2

This example renders a single circle that follows the mouse cursor across an SVG canvas sized to the browser window. The circle's position updates on every mouse movement using React's state management through the `onMouseMove` handler. The visualization uses React 16.9 with hooks (`useState`), ReactDOM to mount the component, and D3 v5 (imported as `d3`) to fetch a CSV of CSS named colors from a GitHub gist, though the fetched data is not used in the displayed output.

Mouse Follower

A circle follows the mouse cursor across a full-screen SVG canvas. The circle's position is bound to the mouse coordinates, updated on every mouse move event. The example uses React with a `useState` hook to manage the cursor position, and the ReactDOM `render` method to mount the component. D3.js is loaded but not actively used in the rendering logic, which relies solely on native SVG elements and React event handling. The circle is drawn with a fixed radius of 30 pixels.

Mouse Follower

This example displays a single circle that follows the mouse cursor across the full browser window. The circle is rendered as an SVG element with its position updated on every mouse movement event. Built with React, the code uses the `useState` and `useCallback` hooks to manage and optimize the cursor position state, while `ReactDOM.render` mounts the component. The SVG viewport is set to the window’s dimensions, and the circle’s center coordinates are directly bound to the tracked mouse position.

React Mouse Follower

A React component renders an SVG circle that follows the mouse cursor across a 960×500 viewing area. The application uses React’s `useState` and `useCallback` hooks to track mouse coordinates via an `onMouseMove` event handler on the SVG element, updating the circle’s `cx` and `cy` attributes in real time. D3 v5 is loaded but not directly used; rendering relies solely on React’s declarative SVG output with a fixed 100-pixel radius circle.

Mouse Follower

A React component renders an SVG circle that tracks the mouse cursor across a 960-by-500 viewport. The circle’s position updates in real time through React’s `useState` hook and an `onMouseMove` event handler on the `<svg>` element, which captures the cursor’s `clientX` and `clientY` coordinates. The example demonstrates interactive SVG rendering with React 16.9, using the `ReactDOM.render` method to mount the application, and relies on a production build from unpkg. The circle maintains a fixed radius of 30 pixels while following the pointer.
