I agree. I'm Norwegian, though I've lived most of my life overseas. I came into it with more background knowledge than most readers in this thread. Nonetheless, I found the visualization somewhat uninformative as well.

That would be a perfect visualization.

A damn fine visualization, though, can still require domain knowledge. For example a medical plot is an excellent visualization of certain parameters, but it does not tell much to a non-doctor. And there are plenty of extra useful visualizations in the sciences that only makes sense when you have extensive domain knowledge -- like most of the plots in engineering papers.
