Data can be pretty confusing to some, but it can also be absolutely beautiful if presented properly.
I'll be totally honest here: data makes my head spin. I'm not the greatest at being able to interpret a whole string of numbers, but I can read a chart like a motherf**ker! The graphical element definite makes complex data much easier to absorb and comprehend, plus it is also just nice to look at.
While numbers make my head spin, however, they also make the world go 'round. Data dominates our lives these days and data analysis can actually be applied to a LOT of things you may not have even thought of - like references to sex/drugs by characters in a popular TV show.
There is a chart for everything.
These might really come in handy at a moment you least expect it, so you may potentially want to bookmark it for later.
