I ran into this chart while looking for examples of XY scatter plots and couldn't resist re-building it, following the instructions outlined way back in 2000 I think. Unfortunately the original link no longer works.

The exercise is to verify the value of pi by plotting the circumference vs. radius of a number of objects measured in a lab. Here is the data:

circumference radius
4.08 0.66
11.94 1.89
13.18 1.98
16.34 2.62
21.78 3.62
30.16 4.78

Here is the original result:
