One Year of Comrades Training

On a recent job at Discovery to do some analytics for Vitality, I was looking at data that is recorded into their platform as part of their insurance linked wellness program. There are various activities that are tracked as part of the program and a fair amount of it is running data. Given the size of their customer base it’s fair to assume that many of them have run the Comrades Marathon, and I wanted to see what all those runner’s various training programs looked like.

Jerry Mander

par_mander_01Since this is an article about gerrymandering, I thought I’d go with a clever, catchy title like Jerry Mander. Ha! But.. it turns out he is a real guy (pictured on the right) with real crazy hair and has written a book about the dangers of television. He also wrote a book about the flaws of capitalism. I get a sense he is just against things (including combs). This article is actually about the other kind of gerrymandering:

n. The practice of redrawing electoral districts to gain an electoral advantage for a political party.

You can read all about gerrymandering online. Its not a new practice. The picture below was published when the term was first coined in 1812.

The_Gerry-Mander_Edit

What I’m wanting to show here is how this relates to a South African context. With the next municipal elections coming up soon, its interesting to see how our electoral system implements the notion of voters vs. voting district. Continue reading “Jerry Mander”

HTML Music Visualiser using D3

I have always dream of a world where all interactive software would work via the browser. But we still have people clinging to their desktop and mobile apps like some weird guy who believes the best years were when he was still in high school in the 80’s. An all browser world will use one programming language and is platform independent. Mostly.. Apart from when it isn’t. While we have a lot of web stuff now, some components have remained firmly out of reach and one that I have often wanted to experiment with is audio. Enter the <audio> tag.

A Timeline of When the World Ended

A recent Naked Data newsletter pointed me to this article on wikipedia which gives a list of when the world was predicted to end throughout recorded history. Its a timeline of when the world was supposed to end, who claimed it would and how/why. It is wikipedia, so its as accurate and complete as wikipedia can be. I figured it would be a nice thing to see on an actual timeline, so here we have it. Continue reading “A Timeline of When the World Ended”

Yet Another IP Attack Map

Screen Shot 2014-09-16 at 12.33.28 PMAttack maps are becoming a more common data visualisation with some great examples that have been doing the rounds here, here and here. I tackled a similar project that has been put on hold for now, but I really enjoyed making the map and I think its a fun interpretation. The version I put up shows the attack data for 1 May 2014.

 

Birthday Graph for South Africa

One of the projects I worked on in 2013 gave me access to a large list of South African ID numbers. Since the South African ID number encodes the person’s birthdate into the first 6 digits, I realised it would be possible to make a South African version of this map of common birthdays in the US.  I grabbed digits 3 – 6 (month and day) of each ID and discarded the rest to be safe. From there, its was simple enough calculate the frequency distribution.  The US map only shows the ranking, not the actual distribution and so I have made an interactive version that does both:
