The FP Group provides global insight and analysis. A friend had shared one of their articles with me, it listed, according to foreignpolicy.com, the 500 most powerful people on the planet.
It was a pretty jive list, but it essentially was this table of 500 people. I felt for such a list, you should be able to sort, filter and even get some sense of aggregate information on the countries listed.
So, I made a bookmarklet that would let me apply those features to the table they provided.
This is what it looked like after I was done:
As I wanted, you could now sort, filter or view a nice chart on the data presented. All right from within the page, thus not having to navigate away.
