This chart plots each city's latitude by its humidity. The x-axis represents the latitude for each city, with 0 being the equator. Positive numbers go farther north on a map and negative numbers go farther south. The y-axis represents the humidity percentage. At the bottom of the chart is 0 (i.e., no humidity) and the top of the chart is 100% (i.e., very humid).

The data doesn't appear to show a relationship between location and humidity. There are cities with high humidity and cities with low humidity at nearly every location.
