With regards to "When I put text onto the graph (suppose for simplicity I want to put the amount % of each zone in each zone centroid), when I set a transparency (alpha <1), the text becomes faded as if the circles were covering it."
Just to update, this is no longer an issue when I export the figure as jpg, etc.; the text appears opaque and not covered by the patches.

Plot 2- or 3- circle area-proportional Venn diagram
Thank you, Darik. I will give that a try.
Another comment/question: when I put text onto the graph (suppose for simplicity I want to put the amount % of each zone in each zone centroid), when I set a transparency (alpha <1), the text becomes faded as if the circles were covering it. Ideally I would like the text to be bold and clear on top of the semi-transparent circles. Anyone else have this same problem, or know of a workaround? Thanks.

@Tong: I suppose you could tweak the position of the circles manually via the returned handles:
%Build the venn plot and return the handles
h = venn(...)
%Shift the first circle by (dx, dy)
set(h(1), 'XData', dx + get(h(1), 'XData'))
set(h(1), 'YData', dy + get(h(1), 'YData'))

Plot 2- or 3- circle area-proportional Venn diagram
I have a 3-circle diagram in which one of my zones is empty (for [z1 z2 z3 z12 z13 z23 z123], z1 = 0), but an area/patch is still drawn. I think if the centroid for circle1 is shifted so that it fits completely inside the other two circles, that would be ok. How can I do this?
