Data visualization tutorial in Processing

Apr 13, 2010

If you absolutely refuse to touch any code, I suggest Many Eyes or one of the fine FD sponsors, but if you’re looking to get your hands dirty, Processing is a great place to start.

Jer Thorp, whose work we saw not too long ago, posts this introduction tutorial for data visualization with Processing.

I’m going to start from scratch, work through some examples, and (hopefully) make some interesting stuff. One of the nice things, I think, about this process, is that we’re going to start with fresh, new data – I’m not sure what kind of things we’re going to find once we start to get our hands dirty. This is what is really exciting about data visualization; the chance to find answers to your own, possibly novel questions.

The examples are straightforward, the results are interesting, and most importantly, it gives you a lot to work off of with your own data and geometry. Hopefully it’s the first post of many.

Visualizing the Uncertainty in Data

Data is an abstraction, and it’s impossible to encapsulate everything it represents in real life. So there is uncertainty. Here are ways to visualize the uncertainty.
