This example displays a summary of a CSV file containing CSS named colors, parsing the data with d3.csv and presenting the file size, row count, and column count in a large-text HTML preformatted block. The visualization uses D3 v5’s CSV parsing and formatting functions, fetching data from a remote gist URL. Although built within a React framework, the interface is purely a React-inspired text layout, not interactive charts. The code also includes commented-out alternatives using fetch() and async/await, showing different loading approaches.
