I'm working with some friends on a small private mini MMORPG game server, and we want to make a PvP event (players VS player) fights, and post the live results on the website as a tree.
I don't know what is it called, I tried every keyword combination on google and this is what I finaly came up with (2 pictures at the bottom).
I need the name of the two types of the trees, what is called so I can do more googling about it.
I also need to know if there is any PHP/HTML/JS or FLASH, Scripts or API or something that can help me accomplish this. I have no problem coding it from PHP/MySQL side, but it looks very hard to render and print on client side, because the tree can get really big if we get alot of players. Please help.
