That's probably the point: the fonts are not embedded in your PDF figure. You can check this in Adobe Reader, by opening the PDF figure then going to File > Properties and selecting the Fonts tab. Or, in case you have the xpdf tools installed, by running pdffonts on this figure. Or opening your .tex file in TeXworks, selecting the Preview window and going to Window > Show > Fonts.

That said, the cure is not simple:

- Either modify your visio + MathType workflow in such a way that the fonts are embedded. I do not have visio, and I have MathType but I'm not using it, so I can't be of much help.

- Make sure the missing font is available in a format TeX can use (PostScript, TrueType, OpenType). Install it at the appropriate place in your texmf trees, then create a .map file for it. Run updmap to include this .map file when creating pdftex.map, or simply add in your .tex file a line like

\pdfmapfile{+mymapfile.map}

Not easy!

Wait: as a test I just created an equation "ax^2+bx+c=0" in MathType then saved it to an EPS file. The EPS file contains

%%DocumentFonts: Symbol
%%+ Times-Italic
%%+ Times-Roman
%%DocumentNeededFonts: Symbol
%%+ Times-Italic
%%+ Times-Roman

telling the fonts are indeed not embedded. Try applying epstopf to it (it's part of TeX Live, at least on the Mac), with the --embed option. Here the resulting PDF file has the missing fonts embedded.
