Loading a CSS named colors dataset via `d3.csv`, this example renders each color as a horizontal strip in a stacked column. React manages the component state and updates the DOM directly, mapping each data row to a styled `<div>` element. The visualization leverages React's `useState` and `useEffect` hooks to fetch the data, while D3's CSV parsing handles the external file. The resulting SVG-less layout uses inline styles with the `RGB hex value` field to display all 148 colors as a simple, data-driven color swatch.
