You don't need to write the code to do the geoip lookup until after you've collected enough data to analyse. If hardly anyone fills out the poll, you don't need to write the code.
"Hard" part that I'm referring to is creation of visualization, choosing the right images [e.g naked woman from renascence painting, naked man from modern magazine] and putting it all together.
I was thinking something more "visualcomplexity.com / flowingdata.com" scale, and less "hotornot" script.
