genetic-origins-heatmap VS slidercards

When I write a program I usually make it focused on a single thing that it's supposed to accomplish. For example, Calligrapher AI lets you type text and then "writes" the same text in human-like handwriting while you watch, and lets you save the image. Beep Knobs is just a board with knobs (albeit a fancy one) that lets you generate customized beeps. And Genetic Origins Heatmap does just what it sounds like, produces a world map indicating where your ancestors came from (using 23andMe DNA data, for example).

Here is an application I wrote that works the same, but is simpler to use. Currently it only accepts 23andMe data but I intend to update it to support AncestryDNA also. I will edit this comment when it's done.

There's an additional flaw that I realize only in retrospect: A naïve heatmap will tend to exaggerate the significance of regions for which there are more datapoints, since they overlap and contribute to raising the temperature for that particular cluster. But this is a minor issue that doesn't fully explain the Switzerland thing. If any programmers would like to help resolve this, here is the source code on Github.

I'm working on an app with a similar theme if you want to check it out here. I can look into adding support for Anki files if you think that'd be cool.
