This example shows the CSS named colors dataset rendered as a horizontal stacked bar chart, where each row is a colored strip corresponding to a color’s RGB hex value. The visualization uses React hooks—`useState`, `useEffect`, and `useCallback`—to manage asynchronous data loading via `d3.csv`, displaying a loading message until the data arrives. React then maps over the parsed CSV rows to generate the colored divs, demonstrating a simple integration of D3’s data fetching with React’s state-driven rendering in an SVG-less, HTML-based layout.
