unit-distance drawing

A unit-distance embedding is a graph embedding in which all edges have unit length. A graph possessing a unit-distance embedding in two dimensions is called a unit-distance graph. A unit-distance graph is a special case of an integral embedding. A graph possessing an embedding that is both unit-distance in two dimensions and planar is known as a matchstick graph.
