Force-directed algorithms are among the most flexible methods for calculatinglayouts of simple undirected graphs. Also known as spring embedders, suchalgorithms calculate the layout of a graph using only information containedwithin the structure of the graph itself, rather than relying ondomain-specific knowledge. Graphs drawn with these algorithms tend to beaesthetically pleasing, exhibit symmetries, and tend to produce crossing-freelayouts for planar graphs. In this survey we consider several classicalalgorithms, starting from Tutte's 1963 barycentric method, and including recentscalable multiscale methods for large and dynamic graphs.
