Graph layout is a field of research in computer science and mathematics that focuses on visually organizing the nodes and edges of a graph in a clear and aesthetically pleasing way. The goal of graph layout algorithms is to minimize edge crossings, optimize node placement, and generally improve the readability and understandability of the graph. Graph layout algorithms can be used in a variety of applications, including network visualization, social network analysis, and bioinformatics. Common techniques used in graph layout include force-directed layouts, hierarchical layouts, and grid-based layouts. Overall, graph layout research involves developing algorithms and methods to effectively display complex networks and graphs in a way that makes them easier to interpret and analyze.
