The link below leads to the master index of my family tree, which contains about 13,000 relatives. Web pages are created on demand with CGI scripting from a GedCom database, and include family pages along with pedigree and descendency charts. The site contains the ability to download a GedCom of ancestors or descendants of any individual. Modifications were made to the scripts to allow viewing of pedigree information of a large number of generations (over 150).
The software that serves this family tree can be found on my GitHub site by following the link below. It includes the modifications to display a large number of generations (over 150) on the pedigree and descendency charts, along with collaspable branches. Feel free to make any modifications and add to the source code on the GitHub site.
