Checkpoint 3: I completed scatterplot.py 

I think it went well. I think I understood how everything fit
together. As I was working, I was thinking that I could really do
this assignment without looking at plotting.py and ticks.py because
of how the steps were broken down, and I'd probably still get an
understanding of using functions to break down problems. In some
ways, I appreciated having plotting.py and ticks.py made for me,
because it kept the focus on breaking down problems as opposed to
focusing on writing all the minutia (like flyto) from scratch. of
course, I did look through them! I wasn't thinking about other
programs I could write--I suppose I'm just focused on the programs
I have to write at the moment, to be honest. I think once I'm caught
up with assignments and have time to plan new curricular materials,
I'll be able to keep the idea of this lab in mind. Given my
background as a math teacher, I imagine I'd want to do other data
visualization tasks.
