Paper Title
A Survey on Advanced Types of Visibility Graphs

In computational geometry and robot motion planning, a visibility graph is a graph of intervisible locations, typically for a set of points and obstacles in the Euclidean plane. Visibility graphs may also be used to calculate the placement of radio antennas, or as a tool used within architecture and urban planning through visibility graph analysis. This is a brief survey on the visibility graphs of simple polygons and their types. Index Terms - Visibility Graphs, Vertex-EdgeVisibility, Bar Visibility Graphs, Invisibility.
