Fantasy map generator

This is fun. It’s a fantasy map generator with the following rules: Project goal is a procedurally generated map for my Medieval Dynasty simulator. Map should be interactive, scalable, fast and plausible. There should be enought space to place at least 500 manors within 7 regions. The imagined area is about 200.000 km2. Just click...

Please help the Delaware Dept of Education

Shane C. asked me to fill out a survey hosted by the Delaware Department of Education. This is a survey about designing their dashboard. And I'm very happy to see that they are doing this. In the survey, you are asked to comment on different ways of presenting certain data, and they want to know which version is "easier to understand". It takes about 5-10 minutes to complete it. The...

Mikaela Shiffrin pulling away for gold

Mikaela Shiffrin won her first gold medal in PyeongChang with a fraction of a second lead. In events where athletes race side-by-side, it’s easier to see how close such a lead is. But with alpine skiing, it feels more like a race against a clock. So to capture some of the dramatics of the former, Derek Watkins and Denise Lu for The New York Times imagined the results had all...

Visual introduction to the Fourier Transform

One of my least favorite electrical engineering courses in college was on signals and communications. I remember there being a lot of Fourier Transforms. I also remember falling asleep a lot, because it was a two-hour lecture with the lights turned off. Maybe if the demos were more visual like this, I would’ve stayed awake. (Probably not.)

Where constituent input ends up

When you have input to send Congress, you have a number of communication options available to you: phone, email, social media, etc. Many of the bigger issues have dedicated sites that help automate some of the process, which of course leads to a large volume of input that lands in a congressperson’s voicemail, inbox, and notifications tab. Where does it all go? The OpenGov Foundation looked into it and produced...

Tracking Historical Twitter Followers: @elisewho vs. @stiles

My wife (@elisewho) and I (@stiles) had a silly social media moment yesterday when I replied to one of her tweets — despite the fact that she was sitting in an adjacent room of our Seoul apartment. USC professor Robert Hernandez (a.k.a. @webjournalist) captured it:   Among my favorite media couples are @elisewho and @stiles. pic.twitter.com/HLp3g90Tgc — Robert is in S. Korea (@webjournalist) February 12, 2018 The exchange, which we both...

Looking above the waist, dataviz style

I came across this chart on NYU's twitter feed.  Growth has indeed been impressive; the dataviz less so. Here's the problem with not starting the vertical scale of a column chart at zero: In a column chart, the heights of the columns should be proportional to the data. Here they are misaligned because an equal amount has been chopped off below 30,000 from all columns. The light purple that I...

If you’re looking for some data to play with, FiveThirtyEight just made it easier to download their data and code. They’ve been on GitHub, I think from the beginning, but this data page is even more straightforward and to the point. Tags: FiveThirtyEight

Who’s Competing at Pyeongchang? A Breakdown By Sports, Nations, Genders

More than 2,900 athletes from 92 nations and territories are competing in the Winter Olympics in Pyeongchang, South Korea. The event has 15 different sports (and many events within each). Which sports have the most athletes? Hockey, which requires a 23-person roster, leads the list, followed by largely individual sports, such as alpine and cross-country skiing: Here’s how those sports break down by the number of competing countries. Again, alpine...

Governor of Maine wants a raise

In a Trifecta checkup, this map scores low on the Q corner: what is its purpose? What have readers learned about the salaries of state governors after looking at the map? (Link to original) The most obvious "insights" include: There are more Republican governors than Democratic governors Most Democratic governors are from the coastal states There is exactly one Independent governor Small states on the Eastern seaboard is messing up...
