Hi, Peter, Doug, and Philip: Thank you so much for your time and input. I appreciate any assistance I can get. Doug, it may not be that tricky. While I'm not completely green to SVG, I've not gone far beyond drawing images and text and attaching hyperlinks to clickable elements. You said that you have seen (and done) similar things in SVG in the past. I am looking for someone with experience and a high level of confidece to point me in the correct direction. Peter: You're absolutely correct, I am building Gantt charts of tasks and subtasks. I apologize for not saying that initially. My tree structure exists in database tables. Currently, I'm simply looping through a linked list and drawing each element in the appropriate x,y place. I have NO idea how to creeate a tree structure in SVG or even if it can be done. Philip: While I have extensive experience with simple graphic techniques, I've never used glyphs before. Most of the elements in a gantt chart are fixed in length (i.e., triangle, diamond, circle) but bars are used to show task lengths from start to finish. Can I use glyphs to show elements of variable length? Mucho Thanks, guys. I look forward to hearing more from you on this topic. Patricia

Unless I'm misunderstanding something, I've seen (and done) similar things in SVG in the past, and I don't recall any particular challenges. I was speaking out against the misuse of glyphs. Too be fair to Philip, though, it's not unheard of in the computing tradition. In the Dark Ages of Computing, many specialized fonts used shape glyphs, for circuit diagrams and maps and other non-text compositional elements, as a kind of old-school 'use' or 'symbol', in order to save memory on frequently-used shapes. There are large blocks of Unicode dedicated to this legacy, and I was told recently that certain industries still use this odd practice.
