Submission + - Potential Constructive Proof of the Four-Color Math Problem

I have updated my original post to address some of the comments made here on Slashdot. Peer review is always good, and thank you all for the insights.

This is a handy tool, but there are many search terms that Google Trends does not display any results for. Such terms (such as "Linux Firewalls" — with the quotes) have insufficient search volumes to display graphs according to the error message that Google Trends generates. Fair enough. Google sets an internal threshold on search volume, and this threshold could be set for reasons that range anywhere from Google Trends is still experimental to Google not wanting to provide data on how it builds its massive search index for emerging search terms. Either way, I would like a way to see search term trends that Google doesn't currently make available to me. So, I've released an open source project called "Gootrude" to do just this. For the past year Gootrude has collected a set of low-volume search terms and interfaced with Gnuplot to visualize them."
