Voronoi diagram from smooshing paint between glass

It feels like magic. I think there’s a magic trick percolating in there somewhere. I’m not sure where this is from. It looks like it’s a recording from a camera pointed at a television screen, so if anyone knows where the original is, please let me know. Tags: paint, voronoi

Higher turnout for midterm elections

Bloomberg charted voter turnout for the just past midterm elections, comparing 2018 against 2014. As you might expect, there are a lot of blue arrows pointed up and to the left. Turnout decreased in only two districts. Tags: Bloomberg, elections

Old Christmas songs get all the play time

Jon Keegan scraped the playlist from the local radio station’s all-Christmas playlist for a few days. Then he looked at play counts and and original composition dates: Considering the year in which each song was written, my dataset spanned 484 years of published music. Of course, many of the older songs are considered “traditional” songs, without a clear writer or composer. One obvious thing about this genre is that it...

The debate rages on about the categorization of food items as soup, salad, or sandwich. Is a hot dog a sandwich? It has meat in bread. At what ratio of solid to liquid does a stew become a soup?

Heatmap shows deaths by age in different countries

You can also compare male and female populations and countries. As you might expect, you can see mortality rates decrease steadily, especially in the younger ages. Spikes or abrupt color changes might indicate war or disease. [via @maartenzam] Tags: age, mortality

Teaching kids data visualization

Jonathan Schwabish gave his fourth-grade son’s class a lesson on data visualization. He wrote about his experience: I’d love to see a way to make data visualization education a broader part of the curriculum, both on its own and linked with their math and other classes. Imagine adding different shapes to maps in their Social Studies classes to encode data or using waterfall charts in their math classes to visually...

A collection of Charles-Joseph Minard’s statistical graphics

Charles-Joseph Minard, best known for a graphic he made (during retirement, one year before his death) showing Napoleon’s March, made many statistical graphics over his career. The Minard System from Sandra Rendgen is a collection of these works. The first section is background on Minard, his famed graphic, and his process, but really, you get it for the collection of vintage graphic goodness. [Amazon link] Tags: book, Charles-Joseph Minard

Millions of data points with deep scatterplots

Ben Schmidt uses deep scatterplots to visualize millions of data points. It’s a combination of algorithm-based display and hiding of points as you zoom in and out like you might an interactive map. Schmidt describes the process and made the code available on GitHub. Tags: algorithm

Measuring the varied sentiments of good and bad words

There was a survey a while back that asked people to provide a 0 to 100 percent value to probabilistic words like “usually” and “likely”. YouGov did something similar for words describing good and bad sentiments. Tags: sentiment, words

Inside Hurricane Maria, a 3-D perspective

This 3-D view inside Hurricane Maria, from NASA’s Scientific Visualization Studio and NASA’s Goddard Space Flight Center, lets you see the data and the lead-up to the storm in a neat 360-degree view. Be sure to watch it on your phone or with a VR thingy for full effect. Disregard the questionable color scale. Tags: 3-d, hurricane, NASA, VR
