For this final checkpoint, I finished the draw_axes(data) and implemented ticks so that plot has clear coordinate reference. The draw_points() function was also finsihed with the use of the no_delay() function which allowed the function to display the points, and done() was used to make the scatter plot visible.

At first, this program was pretty tricky, but working through it step by step helped me understand it.
The top-down plan from Checkpoint 1 made it easier to see how drawing the axes, ticks, and points all fit together. It was difficult to understand
the different parts of the complex program but the top-down plan and outside resources helped me achieve my goal. By the end,
I understood how the pieces worked as a whole, and it gave me ideas for other programs like making line graphs or bar charts in the same way.
