Best web based graphical family tree

I'd like to identify the best tool for generating a graphical web based family tree diagram containing thousands of individuals. It needs:
- good facilities for going straight to an individual by name, date of birth, place of birth and maybe other things
- good facilities for quickly moving around the diagram. This will probably require panning and zooming, and maybe other tools. Genes Reunited's trees are far from ideal here. Often people who are closely related are a long way apart on the diagram. If you zoom out so you can see a lot of people you can't read the writing. Often you end up panning for what seems like miles, following the fourth of 7 parallel lines which you hope will lead you to the ancestor you are seeking, but when you get there you're not quite sure you're still following the right line... There must be better ways.
- ways of filtering, or rearranging the diagram to show the sort of information you are looking for.
- ways of avoiding getting lost. With the GenesReunited system it's ever so easy to spend ages finding the next step in the chain you are following, only to lose track of where you have come from. Maybe it needs to "mark" two or more people so you can quickly get back to them. You also need to be able to see how these individuals are related, which can be very difficult if they are a long way apart on the diagram.
- everyone should be marked with their relationship to a reference individual, e.g. 4th cousin twice removed, great great grandfather etc.
- maybe the diagram needs to be continuously rearranged depending on what you are looking for, rather than having a fixed shape (as it would if it were a large diagram on the wall). Or maybe it needs to have three or more dimensions, with the ability to look at the diagram from different angles in this multidimensional space.
What is your favourite tool for generating family tree charts?
Actually I should include non-web-based tools in this search. The key is to find the right concept for presenting the information and navigating through it - in these days of AJAX I'm sure we can web-ise anything that works well...

Thanks - Rowan
