Intro to Data Structures
************************

We'll start with a quick, non-comprehensive overview of the fundamental data
structures in pandas to get you started. The fundamental behavior about data
types, indexing, and axis labeling / alignment apply across all of the
objects.

Here is a basic tenet to keep in mind: **data alignment is intrinsic**. The link
between labels and data will not be broken unless done so explicitly by you.

We'll give a brief intro to the data structures, then consider all of the broad
categories of functionality and methods in separate sections.
