This example shows the color data from a CSV file of named CSS colors, rendering each color as a thin horizontal strip. The visualization loads the dataset with D3’s `csv` function and uses React’s `useState` and `useEffect` hooks to manage asynchronous data fetching. Each row is mapped to a styled `<div>` element with a background color derived from the `RGB hex value` column. The interface displays a “Loading…” message until the data arrives, and the code also defines a `message` utility that calculates the data size in kilobytes and row/column counts.
