I'm having a tough time figuring out what this sort of tree would be called so that I can search for ways to create it.
I'd like to do a tree where each date of birth aligns vertically with a year, so that you can see the sequence of births visually.
I could make one manually as it's a small tree but I'm not exactly artistic, and I'd love something that would, look nice as well.
My exact case is a funny one - showing when various character types in a Middle earth computer game were created - The good side, with each race, then later, for example the Hobbits are diversified into three different strains, and later still each strain has changes to make them even more different.
All will descend in a tree similar to Tolkien's legendarium, so will be related to his creator and higher powers, and then down in a tree fashion (although usuallly there will be only one parent).
Any ideas on the best way to do something like this?
