Jer over at blprnt.com played around with the newly launched The Guardian API and created some great looking visualizations. He already did similar visualizations with the NY Times API and again he’s sharing his experiences working with the API. In his article Jer focuses on the technical side of creating the visualizations using the API. He leaves out the tools he used for the visualizations but we’re guessing it’s Processing again.
The whole set of visualizations can be found on Flickr.
