Summary:In an embodiment, a process for graph search and visualization includes receiving a query graph, and calculating one or more vectors for the query graph, where the one or more vectors each identifies a corresponding portion of the query graph. The process includes identifying one or more graphs similar to the query graph including by comparing the calculated one or more vectors for the query graph with one or more previously-calculated vectors for a different set of graphs and outputting the identified one or more similar graphs. The comparison with the previously-calculated vector(s) may be based on previously-calculated vector(s) processed by grouping the one or more vectors into at least one group of vectors, identifying a representative graph for each of the at least one group of vectors; and storing the at least one group of vectors and a respective identified representative graph.
