Introduction: I continue to struggle to convey my thoughts on statistical graphics so I’ll try another approach, this time giving my own story. For newcomers to this discussion: the background is that Antony Unwin and I wrote an article on the different goals embodied in information visualization and statistical graphics, but I have difficulty communicating on this point with the infovis people. Maybe if I tell my own story, and then they tell their stories, this will point a way forward to a more constructive discussion. So here goes. I majored in physics in college and I worked in a couple of research labs during the summer. Physicists graph everything. I did most of my plotting on graph paper–this continued through my second year of grad school–and became expert at putting points at 1/5, 2/5, 3/5, and 4/5 between the x and y grid lines. In grad school in statistics, I continued my physics habits and graphed everything I could. I did notice, though, that the faculty and the other

Introduction: I stumbled across a chart that’s in my opinion the best way to express a comparison of quantities through time: It compares the new PC companies, such as Apple, to traditional PC companies like IBM and Compaq, but on the same scale. If you’d like to see how iPads and other novelties compare, see here . I’ve tried to use the same type of visualization in my old work on legal data visualization . It comes from a new market research firm Asymco that also produced a very clean income vs expenses visualization (click to enlarge): While the first figure is pure perfection, Tufte purists might find the second one too colorful. But to a busy person, color helps tell things apart: when I know that pink means interest, it takes a fraction of the second to assess the situation. We live in 2012, not in 1712 to have to think black and white. Finally, they have a few other interesting uses of interactive visualization, such as cellular-broadband infrastructure around

Introduction: Have data graphics progressed in the last century? The first addresses familiar subjects to readers of the blog, with some nice examples of where infographics emphasize the obvious, or increase the probability of an incorrect insight. Your Help Needed: the Effect of Aesthetics on Visualization I borrow the term ‘insight’ from the second link, a study by a group of design & software researchers based around a single interactive graphic. This is similar in spirit to Unwin’s ‘caption this graphic’ assignment.

Introduction: Jeff, Justin, and I write : Gay marriage is not going away as a highly emotional, contested issue. Proposition 8, the California ballot measure that bans same-sex marriage, has seen to that, as it winds its way through the federal courts. But perhaps the public has reached a turning point. And check out the (mildly) dynamic graphics. The picture below is ok but for the full effect you have to click through and play the movie.

3 0.87575173 228 andrew gelman stats-2010-08-24-A new efficient lossless compression algorithm
Introduction: Frank Wood and Nick Bartlett write : Deplump works the same as all probabilistic lossless compressors. A datastream is fed one observation at a time into a predictor which emits both the data stream and predictions about what the next observation in the stream should be for every observation. An encoder takes this output and produces a compressed stream which can be piped over a network or to a file. A receiver then takes this stream and decompresses it by doing everything in reverse. In order to ensure that the decoder has the same information available to it that the encoder had when compressing the stream, the decoded datastream is both emitted and directed to another predictor. This second predictor’s job is to produce exactly the same predictions as the initial predictor so that the decoder has the same information at every step of the process as the encoder did. The difference between probabilistic lossless compressors is in the prediction engine, encoding and decoding bein

Introduction: Jeff pointed me to this article by Nick Berry. It’s kind of fun but of course if you know your opponent will be following this strategy you can figure out how to outwit it. Also, Berry writes that ETAOIN SHRDLU CMFWYP VBGKQJ XZ is the “ordering of letter frequency in English language.” Indeed this is the conventional ordering but nobody thinks it’s right anymore. See here (with further discussion here ). I wonder what corpus he’s using. P.S. Klutz was my personal standby.

Introduction: This one was so beautiful I just had to repost it: From the New York Times, 9 Sept 1981: IF I COULD CHANGE PARK SLOPE If I could change Park Slope I would turn it into a palace with queens and kings and princesses to dance the night away at the ball. The trees would look like garden stalks. The lights would look like silver pearls and the dresses would look like soft silver silk. You should see the ball. It looks so luxurious to me. The Park Slope ball is great. Can you guess what street it’s on? “Yes. My street. That’s Carroll Street.” – Jennifer Chatmon, second grade, P.S. 321 This was a few years before my sister told me that she felt safer having a crack house down the block because the cops were surveilling it all the time.
