This is a screenshot from http://funki.com.ua/ru/portfolio/lab/world-religions-tree/
It attempts to draw a tree structure showing the origins and history of all major religious groups. The +,- buttons let you zoom, and you can pan with the mouse. Since there are occasional schisms and reunifications, the way they have displayed it within the tree structure is interesting. The webpage is, however, not easy to view on a screen. If it were a large poster up on a wall, this might be more effective.
