Relationship Analysis
Relationship analysis is a visualization form you are probably more familiar with
than you know. The earliest exposure you would have had to a visualization
of this type would have been a family tree. Understanding how relationships
work, and being able to tell at a glance which of a set of objects is dependent
on another, is an old but growing area. Especially given the advent of social
media, networks are taken to represent influence; for instance, a marketer
may be more inclined to market to people with many followers on twitter
than to those with only a few followers. Being able to analyze this is thus is
a key differentiator. This chapter skips the pieces of heavy lifting that often
sit underneath these analyses. The tools that would be used for this analysis
include graph databases.

The two different types of relationship analysis we are going to cover in this
chapter are network graphs, which show items at the same level and how they
interrelate, and hierarchical or tree structures, which show the relationships
from the top down. Trees and hierarchies have technical differences in detail,
but for the purposes of visualization, you can treat them the same. You will
be familiar with the Analysis Services hierarchies already from Chapter 13, so
those types of visualization will be excluded.
