This example displays a simple data summary dashboard for a CSV dataset, showing the total row count, column count, and number of unique countries. It uses the D3.js v7 library, specifically the `d3.csv` method to load the remote CSV file and then binds the resulting data to DOM elements. The code appends a styled `div` container with the summary information, using D3’s selection and `html` methods to populate the text. A clean, card-like presentation is achieved through the accompanying CSS stylesheet.
