I quite often use UI mockups to show an example of the end result (or ask others to do the same). It doesn't even matter if it's correct, but it's a useful way to start a discussion. I've tried to do this in words but often different people have different interpretations and it simply doesn't work without a picture.
I've also found it very useful when people are asking for things that don't entirely make sense, such as a chart/report that would require 3+ dimensions. By asking them to draw an example, they realize the challenge and we can make progress.
