Week 7 — Data Visualisation Exercise

Based on the Pollution data set of the Air quality measurements on 41 U.S. cities, I was only able to include 4 dimensions of data, so I decided on what I deduced were data for the City, Population and SO2, to prevent having too many different kinds of data in the visualisation.

From this visualisation, I am able to better tell the relationship between cities, their population, and the amount of SO2 they produce, which contributes to air pollution in the city. The saturation of the circles represent the concentration of SO2 in the air, and the size of the circles represent the population size of the city.
