My intention with geneapraph was it to create a family tree visualization that shows the overlapping of lifespan of generations. By just displaying the lifespan of persons you can also directly see who, at least theoretically, got to know each other.

I tested out many different variations, finally decided for one basic ground structure but two different shapes to display the information. In the more classical view overlapping lifespan is visible more quickly. On the other hand the semicircle view gives a more interesting impression and it is easier to distinguish between father’s side on the left and mother’s side on the right.
