If you are working with an AdjacencyMatrix, here's an additional idea using
Combinatorica.
Needs["DiscreteMath`Combinatorica`"]
am = {{0, 0, 1, 0, 0, 1, 1},
{0, 0, 0, 0, 1, 1, 1},
{1, 0, 0, 1, 1, 1, 1},
{0, 0, 1, 0, 1, 0, 1},
{0, 1, 1, 1, 0, 1, 0},
{1, 1, 1, 0, 1, 0, 0},
{1, 1, 1, 1, 0, 0, 0}};
MatrixForm[am]
(* Your Labels here as a list *)
Lbls = CharacterRange["A", "G"];
g = SetVertexLabels[FromAdjacencyMatrix[am], Lbls];
ShowGraph[g];
