What's the best way to generate a (nice looking) roadmap? [closed]

Question

I'm using internally a simple text list to represent roadmaps. But that's not enough when it comes to present the roadmap to some powerpoint accustomed decision makers.

Do you know of any techniques to generate (nice looking) development roadmaps? How do you produce your roadmaps?

Update: Started a bounty to draw a little more attention.

I think easies way will be to take some background, may be faded logo of company and draw a huge arrow from left bottom corner to right upper. this can be done anywhere. then add axis depending on what you plan to represent: versions or products. then you can add one more axis if you have some other parameter. then add items in circles on arrow according to your plan. here it is. as a sample just google roadman: http://www.google.ru/images?um=1&hl=ru&newwindow=1&tbs=isch%3A1&sa=1&q=roadmap&aq=f&aqi=&aql=&oq=&gs_rfai=

roadmap like this can easily be done in Word or Powerpoint:
