Analysis of systemic effects of dioxin on human health through template-and-anchor modeling

Example of a directed line graph G and its (edge-to-vertex) dual graph G*.
The vertices of G* correspond directly to the edges in G, as indicated by letters a – h. The edges of G* correspond to vertices in G if one edge is entering this vertex and another one is leaving it. For instance, vertex ② in G is represented in the directed dual graph G* through the edges from ⓐ to ⓒ and from ⓐ to ⓓ, because these edges meet head to tail at vertex ② in G.
