# About the tag graph

There currently is a tag . I wanted to change it to graphs because most of our tags use the plural, but it would not let me (supposedly because the tags are too similar). Is there an easy way to change to its plural short of removing it from all questions and then creating the proper form?

Math, Theoretical Computer Science and Stack Overflow all use graph-theory (SO also has some graph theory under graph, together with plots); Math uses graph for a function graph). So we should use graph-theory as well or at least as a synonym. I favor the direction , making the master tag the most explicit one.
