👉 "DeleteGraph.conf" refers to a file in Graphviz's configuration file that determines how graph graphs are drawn, including edge labels, node colors, etc. The value "DeleteGraph.conf" can be found in various directories on a Unix-like system, such as ~/.graphviz/ or on Windows under "Documents\Graphviz\Conf." This file is used by the Graphviz command-line tool to specify how graph graphs are generated and drawn.
