This example displays a minimal summary of a parsed CSV file, showing the approximate file size in kilobytes, the number of rows, and the number of columns in a large preformatted text block. It uses d3.csv to fetch and parse data from a remote GitHub Gist URL, then accesses the resulting array’s length and the columns property to build the message. The code also defines an async fetchText helper, though it remains unused in the final output. The rendering relies solely on plain HTML text within a pre element.
