This visualization displays a summary of a dataset from the Million Song Dataset, showing the row count, column count, and size in kilobytes, followed by the first ten rows as JSON. It loads the data using `d3.json` from a CSV hosted on VizHub, then prints the results as text in a terminal-style layout with green monospace text on a black background. The code uses D3 v5’s `select`, `json`, and `csvFormat` to fetch and format the data, appending `<pre>` and `<hr>` elements to the body.
