I also have many ancestor charts which have the advantage of a predictable number of persons at each generation (except with implexes): 2 n. For instance, I have a descendant chart from the oldest ancestor, but in general descendant charts collect too many people and after ~10 generations the chart becomes too wide. What I finally came up with in recent years where my DB is on the order of 6000 people and still growing is to create smaller “focused” charts on selected parts. This only marginally improved the clarity of the graph, not speaking of the readability of the boxes which were rendered rather small. I output the complete DB as a GraphViz report and I tried to tune the GraphViz source (which required to learn and understand this source) to minimise crossings (if possible) and also to group in different sections of the paper whole branches of the ancestry. Inter-generation connectors tend to cross, making impossible to follow lineage. The mess comes from the fact that a complete family DB is no longer a tree because generations have not the same duration and implexes become relatively frequent when more and more people are involved. I tried this many years ago when I could use a roll-paper A0 plotter but result wasn’t great at all because there were too many people on the graph (only 600 at that time).
