Not the person you asked the question to but, if I may, I would suggest a 2 (or maybe 3) step drilldown. A high level, more condensed, summary-type of chart (kind of like the one seen in the original post) that would give a clear overview of the differences between the various types of instances (OnDemand, Reserved, Spot). And then a way to drill down into instance types and see the details (AZ, Linux vs Windows, etc...) My issues with the current layout are: - all the text blocks in between charts that are not really informative after you've read them once. - The fact that the instance types, data transfer, EBS, etc... are all listed at the same logical level when I make a clear distinction between, on the one hand, all the different instance types and, on the other hand, everything that pertains to an instance (logically underneath an instance).
