Over at the “More Information per Pixel” blog, they go through a case study where they rebuilt a visualization used by a company for monitoring operational issues and reduced it from a complex 34-page pile of charts and graphs, into a single slick page of data.
We receive many questions about “what is the best chart for this situation” or “what colour should I use for emphasis”. These questions are usually attacking the problem from the wrong angle. The one question you need to ask before anything else is “who is this visualization going to be seen by and how?” Is it in a boardroom on a printed sheet or across a trading floor on a plasma screen. Are the consumers domain experts?
