We made a lot of charts in this chapter! Those were just some approaches to visualizing and analyzing a dataset with entities and a value quantifying a type of relationship. The Superset chart, called a partition diagram, is similar to a TreeMap, but it only generates a single level of partitioning. So, I chose to use a TreeMap instead of that, because it provided a more efficient and powerful way to visualize data.
Hopefully, you are now comfortable with using these chart examples for inspiration to upload your own entity-relationship dataset and analyze it in new and different ways.
In the next chapter, we will continue the trend of analyzing geographical regions by working with location data.
