I have an Inkscape image, saved as a PDF, that I am inserting into a .tex document. I am experience some strange rendering issues. Here is my code (the image is saved as D3.pdf):
\documentclass{article}
\usepackage{graphicx}
\begin{document}
\begin{center}
\includegraphics{D3}
\end{center}
\end{document}
Here is a screenshot of what the image is supposed to look like:

Here is what it looks like when I open the pdf output of the compiled .tex file in Preview on my Mac:

I have tried saving the picture as pdf+latex in Inkscape, but it doesn't change anything. I have tried changing the size of the picture in the .tex file. This causes some things to look different. For example one or two nodes will appear or some small arc of one of the ovals. But it still doesn't render completely.
Does anyone know how to fix this?
Side note: When I open the document on my PC, it renders fine. However, when I open the pdf (compiled from the .tex file), the image doesn't appear all at once. It seems to "load" in pieces (first the dots, then lines, then ovals, etc...). This is eventually going in a beamer presentation and so having it load this way is still problematic. But I would really like to get it fixed on the Mac, since I don't know if I will have access to a PC when I give the presentation.
