Like others, I too have the issue of the world map not showing. I've watched your video quite a few times and cannot identify where you speak specifically to getting the world map to show. Because it doesn't automatically show when you run Geolayout.
I ran this one with Gephi 0.10 ver. It works well. When you import csv file, you should choose "Append to existing workspace". Otherwise, Gephi will deal with your nodes and links separately. In addition, delete unnecessary columns in the CSV file.
