This example loads a CSV file containing CSS named colors from a remote URL and displays summary statistics about the data: its size in kilobytes, row count, and column count. It uses the D3 v5 library’s `d3.csv` method to fetch and parse the data asynchronously via promises, then accesses the parsed array’s `columns` property to report the number of columns. The visualization is minimal—a large text display—but it demonstrates the core workflow of loading and parsing tabular data with D3’s CSV utilities.
