Hi!

So far 133 copies of Deep Into Pharo have been sold. I used Roassal2 to visualize countries 

Here is a screenshot:

The data are embedded within the distribution of Roassal2. Just execute:

and you will get the same rendering.

The map builder has attracted some interest. Here is a small example on how you can render you own data. 

First of all, you need some data. Usually, you get data in a tabular table. For example, I just stumbled on http://www.gdbridge.org/gdb_index

I copy and paste the small columns on the right hand side of the web page into a string in a workspace.

I then convert the third column as floats. I paint all countries in white. I then paint countries from the table using the first column as a name, and the third column as a color gradient

Oh… almost forgot. You can export a visualization on the web. Here is the generated HTML for the sells
