As of Version 6.0, GraphicsSpacing has been superseded by the general option Spacings for GraphicsGrid and related functions.
Graph
(Built-in Mathematica Symbol) Graph[{e_1, e_2, ...}] yields a graph with edges e_j.Graph[{v 1, v 2, ...}, {e_1, e_2, ...}] yields the graph with vertices v_i and edges e_j. Graph[{..., w_i[v_i, ...], ...
GraphPlot3D[{v i 1 -> v j 1, v i 2 -> v j 2, ...}] generates a 3D plot of the graph in which vertex v_ik is connected to vertex v_jk.GraphPlot3D[{{v i 1 -> v j 1, lbl_1}, ...
GraphQ
(Built-in Mathematica Symbol) GraphQ[g] yields True if g is a valid Graph object and False otherwise.
GraphStyle is an option to Graph and related objects that specifies styles to use for the different graph elements.
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.
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.
Greater
(Built-in Mathematica Symbol) x > y yields True if x is determined to be greater than y. x_1 > x_2 > x_3 yields True if the x_i form a strictly decreasing sequence.
GridCreationSettings -> {opt_1 -> val_1, opt_2 -> val_2, ...} is a global option that specifies settings for the Create Table/Matrix dialog.
GridFrameMargins is an option for grids that specifies the spacing between the content of the grid and the frame surrounding it.
