They've mislabelled Germany and Switzerland, surely?Their circles have the same centre, so the # eng/pop is the same, as is sci/gdp. But Germany is much bigger. So it must be the bigger circle.
Yes, you must be right. This document was the source for the Science article:http://www.scribd.com/doc/78682496/2012It shows that Germany's R&D was 2.87% of GDP, and Switzerland 3.00%. Multiplying by the GDPs they give shows that R&D in 2012 wasSwitzerland $9.7 B$Germany $84 B
What I don't understand is why the diameters of the circles vary -- or what the diameter is supposed to represent.I could download the entire article, but I tend to distrust those sites that want me to download a non-standard app.
Oh, OK — I missed the fact that the R&D Magazine story is not the source of the chart. I have now downloaded the Science PDF.
Chris: The size of the circles represents the country's total R&D budget. (Sorry, I accidentally cut that part of the caption off.)
