Questions about handling graphs in Mathematica, graph theory, graph generation, graph visualization (Graph, GraphPlot, LayeredGraphPlot, etc.), the built-in Graph data type and the Combinatorica` package.
For the specific graph structures known as trees, please use the tag tree. For combinatorics of Combinatorica` package use the tag combinatorics. For questions on the matrix representation of graphs (i.e. AdjacencyMatrix) consider using the tag matrix.
For questions about graphing functions (e.g. Plot[Sin@x, {x, 0, 10}]), use plotting, not this tag.
