Processing: Case-Shiller Home Price Index
I’ve updated my Processing app to use the latest Case-Shiller Home Price Index data as of May 26, 2009. (For the uninitiated, see my previous post.) Read more
Processing, week 4: Case-Shiller Home Price Indices
See my post of May 26, 2009 for a more up-to-date Case-Shiller Home Price Index graph.
I must admit, I’ve been extremely lazy about reading Visualizing Data or even updating this blog… but, this post should make up for it.
Earlier this week I skimmed a WSJ blog and article on the Case-Shiller Home Price Index and thought to myself “time for a graph!”
For the uninitiated, Case-Shiller tracks home prices in 20 metro areas. As WSJ states, “[the index has] a base value of 100 in January 2000. So a current index value of 150 translates to a 50% appreciation rate since January 2000 for a typical home located within the metro market.”
This program graphs the history of each city’s home price index. Read more
Processing, week 3
It’s been a week and a half since my Processing, week 2 post and I’m still not done with chapter four, “Time Series.” Oh, well.
I’ve been noticing that my Processing programs use a lot of CPU — about 35% on my dual-core, 2 GHz machine. And that’s for a program which just displays static data, like the one below. Read more
Processing, week 2
Today marks the second week I have been learning Processing, a Java-based language for “program[ming] images, animation, and interactions.” In other words, I want to learn how to make useful, pretty graphics.
Over the past year I had seen Processing mentioned here-and-there in various articles, but what piqued my interest was a visualization of US zipcodes. Check it out; it’s awesome.
My guide, at least for now, is Visualizing Data by Ben Fry. I just completed reading the third chapter and thought I’d share an example program. Read more
