+128579 Landry.....these look to be Venn Diagrams
As an example for the second one :
The yellow part could be interpreted as all the citizens of Chicago
The blue part could be interpreted as all the citizens of Illinois
And the green part could be interpreted as all the citizens of the US
Thus....the yellow is a subset of the blue.....and both of these are subsets of the green
What kind of charts are these?
