This example demonstrates how to fetch and display external tabular data directly from a GitHub repository URL, bypassing the need for manual upload. The visualization shows a summary of the dataset’s row count, column count, and file size in kilobytes, followed by the first 10 rows formatted as JSON. The code uses D3’s `tsv()` function to load a TSV file from `https://raw.githubusercontent.com/hopperrr/ellis-immigration-by-ship`, along with `select()`, `csvFormat()`, and `format()`. The dataset originates from the Ellis Island immigration ship records.
