I have a very large data set which I would like to summarise in as small a space as possible, preferably one side of A4.
The data are from a customer satisfaction survey and are Likert-type scales, 5 scales for each work area, with 190 work areas in total. I would also like to represent the response rate on the visualisation somehow, because response rates are very variable and I want management to look at these as well as the actual scores.
If necessary I don't mind somehow reducing the 5 scales down to one (using factor analysis or some such thing). One or two sides of A4 to go to the senior management team who are of course very busy with lots of other things and decidedly non-technical. Use of colour is no problem, in fact would probably be seen as a boon.
It's just occurred to me that representing the order of the work areas, rather than their absolute value, would be OK, but again I don't want to lose the response rate information.
Hope this question isn't too vague, any ideas gratefully received. I am using R and anticipate that this work will involve my learning ggplot2, which I have not as yet got around to.
