I wrote about Trendrr before though I often found it difficult to understand how to use it – well, no more of that.    Trendrr has added some interesting data sources to mashup, like FourSquare.   In this case, I charted how many times the Havana Central Times Square location has been checked in via FourSquare (though honestly, I have to wonder that it’s fully accurate as I would think it’s been checked into way more than 420 times since 2009.

I also noticed multiple listings in FourSquare for some of the same Havana Central restaurants – so maybe that has something to do with the numbers being less than expected.

What’s interesting is you can also chart the number of Shares, LIkes and Clicks on Facebook for a given account – which is really interesting.  You can also upload your own data sources using REST or Excel spreadsheets.   I think you can even combine a couple of charts together.

Very Nice.
