Is it acceptable to graphically illustrate the steps of a research proposal? I am currently preparing a research proposal with limited number of pages. As a picture is worth a thousand words; I was wondering if a graphic illustration could be provided that could highlight the different steps involved in the project. Would providing such an illustration enhance the proposal? I never came across such illustrations. Any directions for the same?
We have used several graphics in a proposal:


to illustrate the problem to be solved
to illustrate extensions of the state-of-the-art,
to illustrate dependencies and relationships between several subprojects.


This was a large joint project (collaborative research centre) in computer science sponsored by DFG (German Research Foundation).
The application was successful, but I don't know whether the taste of reviewers for other disciplines or funding agencies differs.
