GraphQ (Built-in Mathematica Symbol)

GraphQ[g] yields True if g is a valid Graph object and False otherwise.

GraphRadius (Built-in Mathematica Symbol)

GraphRadius[g] gives the minimum eccentricity of the vertices in the graph g.

GraphStyle (Built-in Mathematica Symbol)

GraphStyle is an option to Graph and related objects that specifies styles to use for the different graph elements.

GraphUnion (Built-in Mathematica Symbol)

GraphUnion[g_1, g_2] gives the graph union of the graphs g_1 and g_2.GraphUnion[g_1, g_2, ...] gives the graph union of g_1, g_2, ....

GrayLevel (Built-in Mathematica Symbol)

GrayLevel[level] is a graphics directive that specifies the gray-level intensity with which objects that follow should be displayed. GrayLevel[g, a] specifies opacity a.

Gray (Built-in Mathematica Symbol)

Gray represents the color gray in graphics or style specifications.

GreaterEqualLess (Built-in Mathematica Symbol)

GreaterEqualLess[x, y, ...] displays as x \[GreaterEqualLess] y \[GreaterEqualLess] ....

GreaterEqual (Built-in Mathematica Symbol)

x >= y or x >= y yields True if x is determined to be greater than or equal to y. x_1 >= x_2 >= x_3 yields True if the x_i form a non-increasing sequence.
