This example visualizes the intersection of place names shared between Ireland (IE) and Tennessee (TN), showing 30 matching localities from a larger dataset of Irish cities. It uses XQuery to define the data, with `cities.xqy` creating a list of Irish locations, `count.xqy` counting Tennessee entries, and `match.xqy` filtering for exact name matches. The resulting `matches.xml` file lists each shared city name with a dual `location="IE TN"` attribute. The visualization renders these matched names, likely as a textual or geographic display, relying on the XML output rather than graphical libraries like d3 or Three.js.
