It is simple to add additonal labels and adornments to any graph

Note that there are several variants of this graph in the table to the right,.

The red cycle was created using Graph Theorist's "Arrange Around a Circle" command.

Provide text or geometric adornments to enhance the impact of a graph.

There are numerous built-in classic graphs and also plenty of room to add your own. Additionally, you may save and load entire graphs sets.

Graph Theorist's as well as TikZ output can produce 3D effects in Latex.

Edges can be directed, dotted, dashed, colored, of varied thickness, ans multiple edges are supported.

External labels can be located anywhere and colored.

Graph Theorist will automatically label all vertices (or some set od selected vertices) using letters or numbers. Labels can be centered or external (or both).

An unusual drawing of the dodecahedron

Find all minimum dominating sets. This graph has domination number 6.

Hamilton's Game consists of a dodecahedron labelled with names of cities - and the goal is to visit each city exactly once return to yiour starting location.

Edges can be curved using Graph Theorist's Edge Inspector. And the curved edges are preserved when Exporting to TikZ.

This shows the use of Adornments to label regions and edges.

Vertices can be round or square, balls, various colors, have shadow effects, optional border effects, and of various sizes.

Note that a search of this graph shows that there are 7,167,690 Hamiltonian paths.

This illustrates some of the edge options available in Graph Theorist.

Graph Theorist can produce edges that are oriemted, curved, and with many additional options.

The grid provides one of many ways for precision placement of vertices.

Shadow Effects Accentuate the Vertices

It is possible to color regions any color you like using the color selector.
