This example demonstrates the size and structure of a COVID-19 global deaths dataset by displaying three metrics in a large text readout: file size in kilobytes, row count, and column count. It loads the Johns Hopkins University time-series CSV directly from GitHub using `d3.csv`, then calculates the formatted data’s byte length with `d3.csvFormat`. The results are written into a DOM element via `textContent`, showing how many rows and columns the dataset contains without any visual chart or rendering.
