A toy family tree chart using FLTK.
Inspired by genealogical-tree, a fairly clever chart showing 4 generations: both maternal and paternal, including cousins, siblings, and children. For more details on this, see the wiki.
Maternal grandparents in yellow. Maternal uncle/aunts on left. "You" (red), and sibling (green) center. Paternal uncle/aunts on right. Not shown: parents and paternal grandparents.
Note: the people shown are random entries from random gedcom files from the interwebs. No chronological accuracy is intended.
