There is an interesting recent blog posting at http://www.statsblogs.com/2013/02/18/revisiting-clevelands-the-elements-of-graphing-data-in-ggplot2/
This is interesting for several reasons:
- The author is rereading Cleveland’s book, the primary book for our class.
- It gives you some nice illustrations of dotplots (the focus of your blog homework this week).
- Also it mentions the following good general principles in constructing statistical graphs.
- A graphic should display as much information as it can, with the lowest possible cognitive strain to the viewer.
- Visualization is an iterative process. Graph the data, learn what you can, and then regraph the data to answer the questions that arise from your previous graphic.
