We're looking at Tree Maps this week! If you're trying to show breakdowns of the whole in Tableau, you need to have Tree Maps in your tool kit.
Tree Maps are amazing because:
They're particularly good at representing data with long tails.
They can represent data in a hierarchical structure (we can build Tree Maps within Tree Maps)!
They're space-efficient, and allow us to visualize many dimensions or measures in one view.
Let’s imagine that we work for a restaurant chain and are helping perform an analysis to figure out which items are under-performing. We’ll start with a visual like this...
A student recently asked me how she could create dynamic, color-changing labels based on whether a field passed a threshold. My first response was “Tableau can’t do that.”. My second thought was “How can I make Tableau do that?”
Tree maps are a data visualization used to communicate hierarchical values in a systematic way with nested rectangles. A lot of the tree maps I see look something like this:
I don’t know about you, but I don’t find this to be particularly informative or compelling. I prefer to use tree maps as a way to highlight a few relevant data points. Notice in the dashboard below how I use a tree map to highlight the top 10 items sold.
