Triangular Scatterplot

Block-a-Day #4. French departments (an administrative division that contains multiple districts) are positioned on a triangular plot according to the percentage of their labor force in three categories: I. agriculture, II. industry, and III. commerce, transportation, and services. From an idea by Jacques Bertin.

What I Learned: Rotation transforms never do what you expect on the first try. Actually, I knew that one already.

What I’d Do With More Time: I’m sure there’s a way to get the triangle to rotate smoothly around its center, but I just ran out of time to figure it out. If you know, ping me @cmgiven.

Block-a-Day

Just what it sounds like. For fifteen days, I will make a D3.js v4 block every single day. Rules:

1. Ideas over implementation. Do something novel, don’t sweat the details.
2. No more than two hours can be spent on coding (give or take).
3. Every. Single. Day.
