The ggplot2 package for R is an amazing system for creating entirely new visualizations of data. It allows data analysts to tell a detailed, meaningful and yet easy-to-interpret story about complex and/or unusual data sets.
To promote more data stories being told, ggplot2 author Hadley Wickham has organized a ggplot2 case study competition. Simply create a new visualization of a data set, and post it to the ggplot2 wiki before October 1. The competition announcement is reproduced below, and to whet your appetite check out some of the amazing entries from last year's competition after the break.
We've moved the ggplot2 wiki to a new location to make it more useful: http://github.com/hadley/ggplot2/wiki.
To publicize the new location, we’re organizing a second ggplot2 case study competition. Some great prizes are at stake:
- Grand prize will be a 32GB iPod Touch generously donated by Revolution Analytics.
- Two runner ups will receive a free Use R! book of their choice generously donated by Springer.
To enter, write up a small case study where you’ve found ggplot2 useful and add it to the wiki home page. The deadline for entry is October 1, 2010.
For more info, check out the competition details. Here are some examples from last year's competition for inspiration. Click the images for full-size versions, and follow the links for the R code.
