Tom Sawyer Software is a Berkeley, California company founded in 1992 - the first commercial firm devoted entirely to graph visualization, layout, and analysis. Its low-code platform, Tom Sawyer Perspectives, plus tools like Explorations and the SysML v2 Viewer, let enterprises, governments, and software vendors turn tangled networks of data into readable pictures: fraud rings, supply chains, telecom topologies, and system models. Bootstrapped, profitable, and global, it has spent three decades drawing the lines between things.
