Graphics element documentation
Coxeter-Dynkins graphics on Wikipedia:

These component elements can be strung together to create linear diagrams. They are 23 pixels tall. The elements are variable width, (making them hard to systematically scale with "px" pixel-width codes). This set allows two sorts of nonlinear graphs, a central linear one that can branch up and down, and two rows top/bottom (a and b), that can be vertically connected and looped. They are largely complete for the finite and affine groups, but the triangle groups can't be labeled in general.

The small dots represent the graph nodes of a Coxeter group, while the ringed (circled) and ringed (hollow) nodes are used in the generation of Coxeter-Dynkin diagrams representing the uniform polytopes of Coxeter.

Examples
The can be used to string a large number of these symbols together, with the CDel_ prefix implicit, and elements separated by pipes.

Examples:
 * = : Coxeter group [3,2] as a cross product.
 * = : Coxeter group [3,2] as a single unit. The  notation is otherwise notated as a broken line.
 * = =  3,4,3
 * = =  3,4,3
 * or, or ,  -  or  representation of atomic "holes", for half symmetry [1+,4,3,3], index 2, quarter symmetry: [1+,4,3,4,1+], index 4, and half symmetry [(4,3,4,2+)], index 2.
 * ,, - [3+,4,3] symmetry, index 2, [3+,4,3+] symmetry, index 4, and [3,4,3]+ symmetry, index 2.
