There are plenty of programmer tools for Call Graph generation. Usually, the text they produce is line-by-line indented trees, or maybe descendants grouped under common parent. Ascii-art is uncommon, probably because other formats are more compact or afford better insight. Off-hand, I can't remember anything that would print boxy art, but it might be worth digging in this direction.
