 So everyone, this is Napoleon, the Kamalama who's actually in Alpaca. No applause, please. No applause, please. This is the ambassador for our next speaker. You may have heard of the seminal research paper published in 2010 that is entitled Crowdsourcing Graphical Perception Using Mechanical Turk to Access Visualization Design, the first paper on the scene, definitely what everyone in this room knows about. It featured, it was a PDF that featured bar charts, line charts. I believe there was a scatter plot in there, a histogram. It was early on 2010, a sign of things to come. You may have also used the library polymaps, his second best-known project after the seminal research paper. A library called ProtoViz, and then there is this also this other one Can anyone remember? I think it was the 3D, 3R, RJS. I mean honestly, the next speaker needs no introduction and is working on some really really cool things and is the only speaker at this conference to be officially endorsed by Napoleon, the Kamalama. I would also like to point out that the Kamasash was artisanally made. No clapping please. Okay, well, so a quiet but warm welcome for Mike Bostock everyone.
