Clear flow charts can go a long way in explaining the randomization arms of your study or any other group allocation. There are 2 free options:
Desktop Programs
RFFlow is a free program "for drawing flowcharts, organization charts, and many other kinds of diagrams." You can download a free demo version which does not expire but has a slight limitation on the number of figures in each chart (not a significant hurdle unless you plan to make very large diagrams).
Web-based Services
Gliffy is a web-based tool for flow chart design. Similar to the web word processor Writely, you can invite colleagues to collaborate on a diagram. "Gliffy also stores multiple revisions of the same chart making tracking changes easier. You can even link your flowcharts from your blog or wiki", writes the Digital Inspiration blog.
I used Gliffy to illustrate a post about DPP-4 Inhibitors for Treatment of Diabetes. The diagram is now on Wikipedia.
Draw Anywhere is another web site for making flowchart diagrams in the browser.

Actually, I think I like Gliffy.com the best. It's simple to use and since it's online, there is nothing to download and install.
