Most data has natural hierarchies within it. So far, we've discussed Region, Sub Region, and Country. We used them on the scatter plot to allow the consumer of the visualization to navigate the different levels of the hierarchy, and group (or aggregate) the data at each level.
It's also possible to visualize the hierarchy directly using a treemap. A treemap is a hierarchical visualization and allows easy navigation up and down through the different levels and is the only Spotfire visualization, at the time of writing, that supports clicking up and down through the hierarchy on the visualization itself.
Let's create a treemap showing the relative infant mortality between the different Regions, Sub Regions, and Countries:

It's good practice...
