They're more flexible than that. But let me show you the canonical example. To do this, I'm going to load a few packages, including the new one coreplot is one that I use for a visualization of correlation. So let's start by loading these packages. And then I'm going to come down and load the state data about Google search terms. And I'm going to save just a few of the search terms to be used as examples here. So I'm going to save that as a data frame. Let's take a look at the data down here at the bottom. And you can see we have Instagram, Facebook, retweets, so on and so forth through mortgage as…
