This is a rendition of one of A. V. Hershey's dot fonts from his 1967 paper "Calligraphy for Computers", the "Mathematical" (serif) font. This version is really a hybrid of the original "Mathematical" and "Cartography" fonts, having some symbols such as the circle drawing and map symbols that the "Mathematical" font originally lacked.
