Help loading and converting a .CSV to arrays

Hey, so im a bit new to OFW, but im trying to use it to make some data visualizations for college enrollment data. I have some .CSV files that i want to make arrays for the amount of students enrolled, how many open seats, the course name, etc. Then use these to make some visual info-graphics.

How would i go about doing this?

You should find everything you need there!
