I'm glad I'm not the only one that is confused.

Is it just making graphs about performance?

More or less, yes. Past, present and future performance of various business variables.

It is amazing to me how many industries have similar problems that can be simply abstracted and applied to a larger scope.

We have profiling, they have "business variable monitoring." I love how the same program solves both problems, just needs a repackage.

One key difference that makes business variables more complex to track are the people involved. You need to connect all theses numbers back to individuals and teams that don't stay put. Additionally you should probably be comparing it to ever changing quotas. These aspects come with specific expectations regarding visuals and options available for reporting.

Business analytics is a nebulous term for a wide variety of activities. But for the purposes of this API, "business analytics" means bar charts, pie charts and scatterplots and variants thereof.
