{"version":"1.0","type":"rich","title":"Loading Data with React & D3","description":"This example demonstrates how to combine React hooks with D3 utilities for asynchronous data loading and display. The application fetches a CSV file containing CSS named colors using D3’s `csv` function within a `useEffect` hook, while React’s `useState` manages the loading state—showing “Loading…” until data arrives. Once loaded, it renders a summary message computed in `message.js`, reporting the file size in kilobytes (via `d3.csvFormat`), row count, and column count. The visualization uses React 16.9 and D3 v7, with the fetched data stored in component state and displayed in a styled `<pre>` element.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b99acffab55b43d98f2c350661679d23?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
