OK!
1. Well, turns out I did have the processes set transparently - not sure how that happened. Maybe I inadvertently set them that way. Thanks for catching that!
2. That's also a good idea, unfortunately my task was to have a constant color flow from left to right of different colors, regardless of the actual units used. I will try to push that on a different chart.
3. Well, neat!

4. Well, kinda. I do use the snap to grid and the alignment functions. They're great. That being said, I'd like to use the idea from point #3. If I had adjustable grids, I wouldn't have to zoom in to snap. I also wouldn't have to try as hard to get processes to be the same size. A bigger grid unit = quicker re-sizing and quicker visual adjustment to get the processes to be the same size. This would be similar to using Adobe Illustrator.
5. Well, I'm a big fan of circles. If I look on larger visual data plots, there are dots and circles. This may or may not be worth anybody's time. I know I can place pictures in the program, but I'd rather work in the program without accessing others until the very end.
6. Is exporting to SVG a future possibility? Adobe Illustrator handles SVG fairly well. I'm sure you know that it's the new craze and all that. It can be used in HTML programming AND it's vector-format. Since it's open source, maybe there wouldn't be any legal issues involved. EMF's are hard to work with. When I export the EMF file from Microsoft Word to a PDF (a longer multi-step process than I expected), it takes words that are too long and replaces them with and ellipses. That forces me have to retype everything. Also, Microsoft Word flattens the text when exporting as a PDF. So, I bring it into Adobe Illustrator and re-adjust everything. Whew!
Sorry for all of the ideas/suggestions. I'm also working in D3.js, but I am not adept at javascript yet and while I really enjoy it, I can get lost for days in the programming.
Thanks,
Kirk
