What I want to do is build a graphical (tree) representation of a hierarchical structure. What I have in mind is something pretty simple, ie no links or special effects. The option to collapse/expand the tree would be nice, but not essential.
I have been googling and there appears to be plenty of builder app's, and plenty of CSS solutions, however I would like to keep this to a single file if at all possible.
Source data is in tabular (excel) format - I can see that a number of the CSS solutions use unordered lists as their source, and I can produce this relatively easily (in VBA).
What I don't seem to be able to find is a non CSS option (as usual, the problem is that I don't know the right questions to ask - then again, if i did, I probably wouldn't need to ask in the first place!!)
