A React component renders a D3-selected SVG circle that follows the mouse pointer across the viewport. The example demonstrates unidirectional data flow: mouse events call `setState` to update coordinates, which triggers a re-render passing new state to a `viz` function. It uses `d3.select`, `.join('circle')`, and `.attr` to bind the circle’s position to state properties `x` and `y`. The initial state centers the circle, and the SVG resizes to the window dimensions.

Loading data with react & D3

A circle follows the mouse across the screen using unidirectional data flow in React with D3. The example demonstrates loading data and managing state through a custom `setState` callback, which triggers re-rendering of the SVG via d3-selection's `join` method. The `viz.js` module updates the circle's `cx` and `cy` attributes based on mouse events, initializing its position to the window's center. It uses D3 v7 with vanilla React, rendering through `d3.select` and `selectAll`.

Loading data with react and D3

A React component tracks mouse position in state, rendering a D3-selected circle that follows the cursor. The visualization uses `d3.select` to manage an SVG and `selectAll` with a data join to update the circle’s `cx` and `cy` attributes on each `mousemove` event. Initial state is set to the window’s center, and the circle’s radius remains fixed at 50 pixels. The example demonstrates how D3’s selection and join methods integrate with React’s state management to synchronize UI updates.

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 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 with React and D3

A React component uses D3 and React state to manage data loading and rendering. The `useState` hook stores the data, while event handlers update mouse coordinates. The SVG renders a single circle that follows the cursor across a 960-by-500 canvas. The example demonstrates integrating React's declarative rendering with D3's data utilities in a minimal interactive visualization.

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.

Loading data in react with d3

This example demonstrates a simple interactive visualization where a single circle follows the mouse cursor within an SVG canvas. It shows how to combine React’s state management with D3.js for rendering. The code defines a React component using `useState` to track mouse coordinates, and handles `onMouseMove` events to update the circle’s `cx` and `cy` attributes. It uses `d3.v6` for SVG handling and `ReactDOM.render` to mount the component, with the circle radius hard-coded as 30 pixels.

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.
