Drawing roadmap diagrams
I'm not much of a diagram tool nut, so when it comes to documenting the SCM strategy for a project, I end up using the same notation explained in this book:
It doesn't look like it was made with Visio but you can use Visio to draw time-line diagrams. Haven't used Visio for that purpose yet so I can't tell you how good it is. Quickly looking at it, it does look to have all the right stuff (except maybe how the Mozilla diagram showed the branches)
I don't know, but it looks to me as if the Mozilla diagram was put together manually by drawing tools rather than automatically using a project management or other drawing program. I've many many custom diagrams like this over the years to impress executives and this smells like something that a creative type made rather than a Project or casual PowerPoint user.
