We study unit disk visibility graphs, where the relation between a pair of geometric entities is defined by not only obstacles, but also distance them. This particular graph class models real world scenarios more accurately compared to conventional graphs. first define and classify then show that 3-coloring problem NP-complete when model used for set line segments (which applies points) polygon...
