VertexCount[g] gives a count of the number of vertices in the graph g.VertexCount[g, patt] gives a count of the number of vertices that match the pattern patt.

Mathematica allows convenient automated selection of plotting and image regions using a family of specially developed robust algorithms, as well as allowing detailed manual ...

In Mathematica , many kinds of data are stored in tables or lists. Mathematica provides many useful functions for creating and manipulating these tables.

HighlightGraph[g, {a_1, a_2, ...}] highlights the a_i that can be vertices, edges, or subgraphs of g.HighlightGraph[g, {..., w_j[a_j], ...}] highlights using the symbolic ...

DirectedEdge[u, v] or u \[DirectedEdge] v represents a directed edge from u to v.

UndirectedEdge[u, v] or u \[UndirectedEdge] v represents an undirected edge of a graph with vertices u and v.

PlotRangeClipping is an option for graphics functions that specifies whether graphics objects should be clipped at the edge of the region defined by PlotRange, or should be ...

To control how a 3D surface responds to simulated light, set its reflection properties. Mathematica lets you control the diffuse reflection of light on a matte surface and ...

 

You may want to export a graphic for use outside Mathematica . You have a large set of choices of raster and vector formats.
