{"version":"1.0","type":"rich","title":"react d3 state example","description":"This example shows a React application that fetches CSS named colors from a CSV file and renders them as a vertical stack of 900-pixel-wide horizontal bands, each colored by its corresponding RGB hex value. The visualization uses React’s `useState` and `useEffect` hooks to load data asynchronously via d3’s `csv` function, mapping each row to a styled `div`. A separate `BackgroundCircle` component (not used in the main view) defines a yellow circle with black stroke, while the `message.js` module computes data statistics. The page is styled with a large `pre` element as a placeholder.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/859bce1461e24d5bb8f956966a0d3225?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
