As long as you came up with it, it is original. I came up with this pie chart totally independently and it did pretty good. Months later there was a repost week and reallyitsjohn posted a very similar pie chart and I thought it was very flattering that he used my idea...then I checked the date created and it was months before mine. I felt so embarrassed because I'm sure there were users that thought I stole the idea from him...doh! :-)
