The theme for this interaction is ‘Facts about coffee around the world’. This example consists of:
1) an introduction view with title and instructions,
2) an illustrated world map with six hotpots, and
3) an open fullscreen popup window with more information about the particular fact.

What is that example intending to do? When should the user use such a theme?
This example is a great and creative way of presenting information that is linked to geographical locations. It is also very practical for large amounts of text.
