A circle follows the mouse cursor, updating its position in real time. The D3.js library manages the SVG canvas and circle rendering, while a unidirectional data flow pattern uses a `setState` callback to pass new coordinates from the `mousemove` event into the visualization state. The SVG is sized to the browser window, and the circle has a fixed radius of 50 pixels.

mouse 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 example uses React state to track mouse coordinates via an `onMouseMove` handler, then renders the circle at those coordinates. The SVG viewport is 960 by 500 pixels, and the circle has a fixed radius of 30 pixels, demonstrating a simple interactive pattern without data or animation.

Data Visualization

A circle follows the mouse cursor across an SVG canvas, with its position updating in real time as the user moves the pointer. The React component uses the `useState` hook to track mouse coordinates, which are passed to the circle's `cx` and `cy` attributes. The `onMouseMove` event handler updates the state on each movement, while D3 v7 handles the SVG rendering within the React framework.

Mouse Follower

A single circle follows the mouse cursor across an SVG canvas, updating its position in real time. The visualization demonstrates React’s state management and event handling, using the `useState` hook to track cursor coordinates and the `onMouseMove` event to update them. The circle’s center is bound to the `mousePosition` state, and its radius is fixed at 30 pixels. The code renders the scene with React and ReactDOM, while D3 is loaded but not explicitly used in the visible logic.

Hello HTML

A simple interactive SVG circle follows the mouse pointer across a 960-by-500 blank canvas, updating its position in real time. The visualization uses React 17 with the `useState` hook to manage the circle’s coordinates, which are updated on every `mousemove` event on the SVG element. The circle’s center is set via the `cx` and `cy` attributes, while D3 v5 is loaded but not directly used in the rendering logic. The example demonstrates state-driven updates in a React-rendered SVG without any external data source.

Mouse follower

A circle follows the mouse cursor across an SVG canvas, updating its position in real time. The example demonstrates basic interactivity in a React component, using React's `useState` and `useEffect` hooks along with an `onMouseMove` event listener to update the circle's center coordinates. D3.js version 5 is loaded via CDN, though the primary rendering is handled by React and SVG elements directly, with the circle styled using default attributes. The visualization runs in a full-window 960x500 viewport, showcasing simple state-driven DOM updates.

Moving circle

A moving circle follows the mouse cursor across an SVG canvas, changing to a random RGB color with each click. The visualization uses D3's data join pattern, binding arrays of null values to create and update a single circle and svg element on every state change. Mouse and click event listeners call a setState function that updates the circle's x and y coordinates to the cursor position or assigns a new randomly generated color.

Mouse following Circle

This example shows a single circle that follows the mouse cursor as it moves over an SVG canvas. The circle’s center coordinates are updated on every mouse movement event, re-rendering the shape in real time. Built with React, it uses the `useState` hook to manage the mouse position and an `onMouseMove` handler on the SVG element. The visualization demonstrates a straightforward interaction pattern, rendering with ReactDOM and the SVG namespace, with no data source involved.

Mouse Follower

A circle follows the mouse cursor across a 960 by 500 pixel SVG canvas, updating its position in real time as the pointer moves. The visualization is built with React (using the `useState` hook) and renders the circle via an SVG `<circle>` element. Mouse movement is captured through the SVG's `onMouseMove` event handler, which updates the circle's `cx` and `cy` coordinates. The example uses D3.js v7 and ReactDOM to render directly into the page's root element, with no external data source.
