Showing convex hulls for a graph where a hierarchy exists

Hierarchical graphs are graphs in which hierarchical relationships exist between the members and hence the graph can be visualized with multiple levels.

A simple example of a hierarchical graph is a family tree. In a family tree, each member is depicted as a node; a relationship (or an edge) exists between two nodes if they are spouses or if they have parent-child relationship between them. This tree can be represented as a hierarchical graph visualized as a vertical-levelled graph with members at each level belonging to the same generation.

A convex hull for a set of points (in our case, nodes of the graph), in simplistic terms, is the minimal closed structure that would enclose all the ...
