Asymptote not showing

Asymptote not showing

I have the package \usepackage[inline]{asymptote} and I am trying to
display the following Asymptote figure:
\begin{asy}
size(200);
pair A,B,C,D;
A=(0,0);
B=(200,0);
C=(200,150);
D=(0,150);
draw(A--B--C--D--cycle);
label("A",A,(-1,0));
label("D",B,(0,-1));
label("C",C,(1,0));
label("B",D,(0,1));
label("E",(200,85),(1,0));
dot((200,85));
draw((0,0)--(200,85));
draw((0,150)--(200,85));
label("$\ \ \ \ \ \ \ 30^\circ$",anglemark((200,85),D,C),SE);
label("$80^\circ \ \ \ $",anglemark(A,(200,85),D),W);
\end{asy}
I'm just getting a blank. No error messages but it's showing nothing. I'm
using TeXShop on a Mac, if that helps any. Any help would be highly
appreciated!
