For the 2007 Scripting Games, I had created a graph HERE of the total entries per each category: VBScript beginner, VBScript advanced, PowerShell beginner, and PowerShell advanced.
I only printed countries with more than 5 entrants though.
I just got a 2008 version to work (except for something minor with "USA" that I'll have to check).
I'll post the results after the games. It doesn't look like the number of PowerShell entrants will surpass VBscript entrants. There appears to be quite a few Perl entrants, which is cool.
I'll also try to post a 2008 version of the per country maps I did HERE in 2006.
