Loading and Parsing CSV Data
This example displays a large text readout showing the size, row count, and column count of a CSV file loaded from a GitHub gist. It uses d3.csv to fetch and parse the remote dataset, then computes the formatted size with d3.csvFormat and inspects the resulting array’s length and columns property. The visualization is purely textual, rendered into a <pre> element, demonstrating basic data loading and parsing workflow in D3 v5.
