The agency I am working for is trying to streamline our processes, and get everyone using the same software. Right now, we have everyone using different software for creating visual sitemaps. Some people use Illustrator, some use Free Mind, xMind, Lucid Charts, etc.

I really like xMind for mapping, and would like to find a free solution that is similar, and easy to use for those who aren't that tech savvy. I had a few people in the office using FreeMind, but it was too complicated for a few of them. We also need something that allows us to export to more formats (such as PDF) than xMind does.

Can anyone provide some suggestions for me?
