A circle tracks the user’s mouse movements across a full-window SVG canvas, updating its center position in real time. Built with React 16.9 and D3 v7, the app uses a `useState` hook to store mouse coordinates and a `useCallback` handler to capture `clientX` and `clientY` from the SVG’s `onMouseMove` event. The circle’s `cx` and `cy` attributes are bound directly to that state, with a fixed radius of 30 pixels. No external data is loaded; the visualization purely demonstrates interactive event handling and state-driven rendering.

A Program that follows your mouse with a circle

A circle follows the mouse cursor across a full-screen SVG canvas, updating its position in real time. The visualization uses React state to track the cursor's clientX and clientY coordinates, triggered by an onMouseMove event handler on the SVG element. Built with React 16.9 and D3 v7, the circle is rendered directly as an SVG `<circle>` element, with its cx and cy attributes bound to the current mouse position. No data source is involved; the interaction is purely event-driven.

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 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.

Loading Data with React & D3

This example demonstrates a simple interactive visualization built with React and D3, where a circle follows the user’s mouse movement within an SVG canvas. The app initializes the circle at the center of a 960 by 500 pixel viewport, then updates its position on every mouse move using React’s `useState` and `useCallback` hooks. The SVG’s `onMouseMove` event handler captures the cursor’s client coordinates and passes them to the circle’s `cx` and `cy` attributes, rendering the result via `ReactDOM.render`. No external data loading is involved; the focus is on state-driven, real-time updates.

Interaction with react

A circle follows the mouse cursor within an SVG canvas, demonstrating interactive state updates in React. The app tracks mouse movement via the `onMouseMove` event handler on the `<svg>` element and updates the circle’s `cx` and `cy` attributes using React’s `useState` hook. The visualization combines React 17 with D3 v7 for rendering, using a simple SVG `<circle>` element with a fixed radius. The code explicitly manages the circle’s position in React state rather than using D3’s data-binding, highlighting the interaction between React’s declarative model and SVG.

Mouse Moving

A full-screen SVG scene tracks the mouse cursor with a single circle that updates its center coordinates in real time. Built with React’s `useState` and `useCallback`, the `handleMouseMove` event captures `clientX` and `clientY` from the SVG’s `onMouseMove` listener, then re-renders the circle’s `cx` and `cy` properties. React 16.9 and D3 v5 are loaded via CDN, with the circle’s radius fixed at 30 pixels. The visualization demonstrates declarative state-driven rendering without any data source or animation.

Loading data with d3

A full-screen SVG circle follows the mouse cursor, demonstrating how React state tracks changing pointer coordinates in real time. The example uses React’s `useState` and `useCallback` hooks to update the circle’s `cx` and `cy` attributes on every `mousemove` event. Rendered through ReactDOM, the SVG’s width and height match the browser window dimensions, while the circle’s radius is fixed at 30 pixels. No external data loading or D3 utilities appear in the visible code, despite the title.

ReactD3.1

The example shows a single circle that follows the mouse cursor across an SVG canvas, with its center position updated in real time. It uses React’s `useState` and `useCallback` hooks to track mouse coordinates via an `onMouseMove` event handler, and renders the circle with SVG elements. The visualization relies on React 16.9 and ReactDOM for rendering, with no additional D3 modules or data sources, demonstrating a minimal integration of interactive state management with SVG output.
