Treemap

1 dimension (hierachical or not) + 1 metric

Represents a hierarchical dimension by encoding a metric on each node of the hierarchy. Example : The hierarchical dimension of geography. On the first level, we can see the distribution of the metric between continents. We can then explore a continent to see the distribution between countries, etc.

A simple example

Try it with your own data on the Visualization Playground

Let's analyze a bit

At a mere glance, we can see that nearly have of your visitors are in Europe, a quarter in the Americas, the remainder in Asia, and but a few in Oceania and Africa.

The “Explore” button gives us a closer look at Europe, revealing that half of those visitors are in the West and the rest are split evenly between North, East, and South. Another “Explore” click and we see that more than half of your Western Europe visitors are in France.

A look at the Americas reveals that the United States accounts for 86% of viewers on the continent.
