Size Evolution of the Ozone HoleJoe Mako left a comment on my previous post critiquing the use of bubbles to represent the size evolution of the ozone hole. I agree with what Joe said: "a bar or line would have been better." The only problem with using a line is that there is not a consistent time measure (1996 throws it off...yes I know, a minor issue).
So I recreated the data with two bar charts. (1) Representing the actual values and (2) the change from the previous measure. I like (1) better. How about you?
