SVG map of Puerto Rico, without county subdivisions.
Based on Puerto-Rico-locator.png, which is itself based on a Public-Domain map from the Central Intelligence Agency (USA)

Using Inkscape, the background of the islands map was traced, then an exclusion cut (exclusive or) was made with a rectangle of the same width and height.  A background was added and the background and islands foreground were grouped
