Beautiful map on unemployment rates on datosmacro.com. If you go to the website you can click on each town and see its name and unemployment rate.
Notice the clusters of high unemployment in Castilla La Mancha, Cádiz-Huelva-Sevilla, and León-Galicia.
The map, however, is misleading if you try to infer comparisons of regional unemployment. For instance, it would seem that Galicia's (northwest) unemployment rate is much, much higher than Catalonia's (northeast). Wrong: Galicia's jobless rate in 2015:Q1 was 21.8%, whereas Catalonia's was 20.1%.
