Ternary Color Scheme

I was interested in the data for the age of European populations, but I found myself more taken with the color scheme used in the visualization:

Ternary Representation of European Populations by Age (Web Size)

A full-sized version of the image is available on request — it’s really big. But the map is part of an article in The Lancet.

Implying Comparison

This kind of data presentation strikes me as close to disingenuous. I understand that somewhere in someone’s mind, the thought is to maximize the width of the diagram, but when all the measures are the same, these all represent percent changes of opinion among the same population responding to the same survey, then the shift in scale actually misleads readers, who easily see the big red bars, that there has been large changes across the board. Instead, there’s been changes of 20%, 15%, and 7%. Those differences in size are hard to read with the light gray numbers up above, almost lost under the bold black of the diagram’s title.

You can do better, The Guardian.

Top 10 Python libraries of 2016

Tryo Labs is continuing its tradition of retrospectives about the best Python libraries for the past year. This year, it seems, it’s all about serverless architectures and, of course, AI/ML. A lot of cool stuff happening in the latter space. Check out this year’s retrospective and also the discussion on Reddit. (And here’s a link to Tryo’s 2015 retrospective for those curious.)

Flowingdata has a list of their own: Best Data Visualization Projects of 2016/. If you haven’t seen the one about the evolution of bacteria that is a “live” visualization conducted on a giant petri dish, check it out.

European Language Tree

I love visualizations like this one, and I can imagine compiling more like this one — a good visualization of the new “tree of life” — as well as a really nice rendering of the periodic table into a *things you need to know* book/portfolio.

EDIT: *I forgot to note that [Ethnologue](http://www.ethnologue.com) is a great resource for language information.*

Dear Data

[Dear Data][] revisits the idea of correspondence with the twist that the two correspondents are designers who gave themselves the task of visualizing a week’s worth of data drawn from their own lives: animals seen, sounds heard, time spent alone.
