Hah! That's just perfect.
A while ago I thought there was a good and a bad way to represent data. Over the years and through some experience I've come to understand that just like any other form of communication, data visualizations tell a story first and foremost. Sure, there are plenty of bad ways to tell a story but there is not a good way to graph any phenomenon. The key to calling bullshit I think is to see the discrepancies between what the data says and what story its graph says.
