Visibility Graphs

Visibility graphs are a way to represent the relationships between points or regions based on their line-of-sight connections. Imagine a set of points or polygons; a visibility graph connects two points with a line if nothing blocks their view of each other—meaning you can draw a straight line between them without crossing any obstacles. This concept is useful in fields like robotics, computer graphics, and geographic information systems to analyze pathways, obstacle avoidance, and spatial organization by translating complex environments into networks of directly visible connections.
