From the post:
Last Saturday, the New York Times published a feature article on the wealthiest 1% of Americans. The on-line version of the article included interactive features like this interactive map showing where your household ranks in the country and in local regions. The print edition, however, included some different (and necessarily static) representations of US wealth data, such as this map of where the wealthiest 1% live:
Interesting for a couple of reasons:
First, the ease with which the initial mapping was done using R. Meaning that you can quickly map/experiment with mappings using R.
Second, consider that R was the vehicle to map the data onto the map. Could have just as easily mapped campaign finance records along with the top 1% data. What subject you decide to map together is entirely up to you.
