When I like to visualize data, I am mostly using the gglot2 library in R. My impression is that this package provides the most advance data visualization environment in R. But there is one thing, that you can’t do with ggplot2: Creating interactive graphics.
There is a fair number of tutorials in the web. I recommend to get your hands on Visualizing Data written by one of the developers of Processing, Ben Fry. It has some where useful examples and is written super accesible.
Other tutorials I found useful:
- Several adaptions of the Processing code from the book above to processing.js compatible code
- A very good example how to integrate processing.js with jQuery
There is one thing, that took me a while to recognize: If you use processing.js you need to put the processing code inside the html body-tag! If it is outside (in the head-tag), it won’t work.
