A React and D3 example demonstrates how to track and render the mouse position as an SVG circle that follows the cursor across the full viewport. The code uses React’s `useState` and `useCallback` hooks within an `App` component, handling `onMouseMove` events on an `<svg>` element. The circle’s coordinates update directly from `clientX` and `clientY`, with all dimensions set to `window.innerWidth` and `window.innerHeight`. No external data is loaded; the visualization relies solely on user interaction and SVG rendering.

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.

Loading data with react & D3

This example demonstrates how to load and manage data in a React application using D3 utilities, with React state tracking the current mouse position. The visualization renders an SVG circle that follows the cursor as it moves across the screen, with the circle’s center coordinates tied directly to the `mousePosition` state. The code uses React’s `useState` and `useCallback` hooks, along with ReactDOM to mount the component, while D3 is imported for data handling. The SVG viewport is set to 960 by 500 pixels, and the circle radius is fixed at 30 pixels.

Loading Data w/React and D3

This example demonstrates loading and managing data in a React visualization, where a single circle follows the mouse cursor across an SVG canvas. The app uses React’s `useState` hook to store the cursor’s x and y coordinates, and a `handleMouseMove` callback updates this state on every mouse movement. Rendering is handled by ReactDOM, which outputs the SVG circle with its position bound to the state. The code explicitly imports React and ReactDOM, and uses `useState` and `useCallback` for state management and event handling.

Loading Data with React & D3

This example demonstrates how React state manages and updates an SVG circle’s position in response to mouse movement. The App component uses the useState and useCallback hooks to track the cursor’s clientX and clientY coordinates, updating the circle’s cx and cy attributes on every mousemove event within the SVG element. Built with React 16.9 and rendered through ReactDOM, the visualization creates an interactive circle that directly mirrors the pointer’s location on the 960×500 canvas, with a fixed radius of 30 pixels.

Load data with React and D3

A React component renders an SVG circle that tracks the mouse position across a 960-by-500 viewport. Using React’s `useState` and `useCallback` hooks, the component updates its state on every `onMouseMove` event, passing the new `clientX` and `clientY` coordinates to the circle’s `cx` and `cy` attributes. The example demonstrates integrating React’s declarative rendering with SVG markup without relying on D3 for data loading or manipulation.

Loading Data with React & D3

This example demonstrates how to load and interact with data using D3 utilities within a React application. It renders an SVG circle that follows the mouse cursor, updating its position through D3’s event handling. The code uses `d3.select` to append an SVG element and a circle, then attaches a `mousemove` listener to update the circle’s `cx` and `cy` attributes based on cursor coordinates. The visualization is rendered via SVG, with the React app serving as the container for the D3-generated elements.

Loading Data with React & D3

This example shows a simple interactive visualization where a circle follows the mouse cursor across an SVG canvas. React state tracks the cursor's current x and y coordinates, updating the circle's `cx` and `cy` attributes on every mouse movement. The code combines React’s `useState` and `useCallback` hooks with ReactDOM to manage the UI, while the SVG scene renders a single circle element whose position is bound to the live mouse data. The interaction is driven by the `onMouseMove` event handler on the SVG, demonstrating direct state-to-rendering synchronization within a React-D3 pairing.

Loading Data with React and d3

This example demonstrates an interactive circle that follows the mouse pointer across an SVG canvas in a React application. The circle’s center coordinates update dynamically based on cursor position, handled through React state and the `onMouseMove` event. The code uses React 16.13.1 with `React.useState` and `React.useCallback`, rendering to the DOM via `ReactDOM.render`. No external data is loaded; the visualization relies solely on user input to drive the black circle’s movement within a 960x500 viewport.
