This example demonstrates how to load and display data using React and D3 utilities. It fetches a CSV file containing CSS color names and their RGB hex values, then renders each color as a horizontal bar with a fixed width and height. The code uses React’s `useState` and `useEffect` hooks to manage the asynchronous data loading, while `d3.csv` parses the remote CSV. The visualization shows a series of colored blocks, each representing a distinct color entry from the dataset.
