Here we can see how City Latitude is plotted against Cloudiness. It is important to first recognize that this data only represents a fixed moment in time on an individual day. Interestingly, when looking at the cities in the dataset that have a latitude of 20+ degrees, one can observe a large concentration of cities that have a cloudiness level of 70%+.
It is also significant to see that there are a large amount of cities in the dataset that show either no clouds in the sky (0% cloudiness) or small patches of blue sky (75%+ cloudiness) at the given time in which the data was obtained.
