Reader Daniel L. points us to this "dashboard" of statistics concerning downloads of a piece of software presumably called "maven". This sort of presentation has unfortunately become standard fare.
Daniel was shocked by the pie chart. Just for laughs, here is the pie chart:
Is it an accountant who cares about every single download (thus needing the raw data)?
Is it a product manager who cares about the current run rates, and the mix of components downloaded?
Is it an analyst who is examining trends over time, aggregate of all components?
In other words, the first order of business is to identify the user.
