simiple animated graphs with processing
Apr 28th, 2009, 10:05am  

I'd like to make cool data visualizations like the ones at gapminder dot org (animated graphs of U.N. statistics).

From what I've read they created their own software and then sold out to Google. Google allows you to use the visualizations- but only to add into other google applications like iGoogle.

Is anyone trying to do something similar in processing? If not, maybe I'd like to be that person. In that case, what are people's favorite libraries to open a file and parse csv? Can one use normal java io classes to do this?

Thanks for any help,
-j

reading CSV files thread
Actually, if CSV data is simple (unquoted), use loadStrings() for example and on each line, use split().

Hi j,

I am working one such things but more on dynamic cartogrpahy so far.

For your work on importing data, I advice you to have a look on SQLite technology. It allows you to use a really tiny SQL database which is much better to handle large amount of data (my point of vue).
Of course you have to know SQL syntax.

some links :
SQL processing library : http://bezier.de/processing/libs/sql/
sqlite manager as firefox extension :
https://addons.mozilla.org/fr/firefox/addon/5817
This extension allows you to build your database from CSV.

To go on such data viz, I identified (not tested) the prefuse java library
prefuse.org

Keep me posted with your dynamic chart project.

Paul
