People who come from the school of Tufte would probably hate a lot of these, because there are much simpler, easier to understand ways to communicate not only the information itself but its significance.
But that may not be the point. The point may be to give preference to aesthetics over clarity, and if so, they've succeeded. Just about every postcard looks like an art print.
I am not a data viz designer, but I've read VDoQI and I enjoy following the field as a lay person. I build a lot of charts but I don't design them. A lot of my clients have philistine data viz taste--and many of their graphic designers too, even the ones whose graphic design taste is good. By Tufte's criterion of information density, their ideas are a total failure: streetlights, speedometer-like gauges, etc. But often they just don't have that many numbers to show, or the numbers have few dimensions. Maybe in that case Tufte would recommend a plain old table, but that isn't always helpful for "at a glance" reading, especially if there is a lot of non-numeric data too. I'm starting to think that Tufte is really excellent inspiration when you have a "hard" data viz problem, but he might lead you astray when you have an easy one. His crusade against chart junk is probably relevant any time though. :-) Anyway, I'm usually just the implementer, so I'm curious what real professionals thing about all that.
I see far more similarities between Tufte and Lupi's work than differences (and works/talks by both of them are among the biggest influences on my approach to visualization and things I want to work on).
Both have as driving principles that people are curious and intelligent, and that visualizations should cater to that. Tufte certainly preaches "avoid unnecessary ornamentation". But he also preaches "show the data". In particular, showing individual data points, rather than aggregations, and that the purpose of a visualization is as much to provoke questions as to answer them.
These are lovely. I like how the informal setting allows for experimentation with really non-standard forms of visualization, the readability of the data varies but they're all beautiful. I especially like all of Stefanie's symbols, and Giorgia's mirror visualization.
You should consider getting a PO Box for guest submissions - I know I'd love to make one!
Tangent: I wonder how interesting (or useful/useless) it would be to train an image classifier using http://www.onemilliongiraffes.com/ and then start looking at a bunch of random pictures.
Fantastic! My only complaint is the lack of higher resolution scan - there's so much detail in these graphs that it's hard to make it all out. Fortunately, you can change the image URLs to see a larger size by changing the "format" parameter, e.g. "?format=original":
This seems like it might even scale to elementary school type projects. Maybe not for all the students, lol. But I bet a few of those kids that like to wear button-up shirts and carry briefcases to class would love the heck out of it. Maybe even a new kind of pen-palling.
There are kids that wear button-up shirts and carry briefcases to class??
...I think we went to very different schools...
That having been said, this could make for a really interesting and thought-provoking pen-pal-type program. In particular, the visualizations relating to personal interactions or how time is spent could really highlight cultural differences that we're usually oblivious to.
Few and far between, maybe 1% of 1% of 1%... but they're out there. So, one or two kids in every district, or a 10% chance of one kid in any one school. Where'd I get these stats? Thin air.
But that may not be the point. The point may be to give preference to aesthetics over clarity, and if so, they've succeeded. Just about every postcard looks like an art print.
