[tex-k] CWEB suggestion; include section for diagram visualization

[Andreas Scherer]

Hello,

CWEAVE produces 'plain TeX' output, so you can do in the TeX parts 
whatever you like.

(1) DEK uses '\input epsf' with Metapost graphics in many of his example 
programs (https://www-cs-faculty.stanford.edu/~knuth/programs.html)

(2) SVG graphics can be included in 'plain TeX' (requires advanced TeX 
engines like pdfTeX, XeTeX, or LuaTeX) with
     \input graphicx.tex
     \includegraphics{[your graphic here.svg}
     \bye
(See 
https://tex.stackexchange.com/questions/63789/inserting-an-image-in-plain-tex 
for more suggestions.)

(3) Somewhat stale, but still available is 'cweb-latex' (not tested): 
https://ctan.org/pkg/cweb-latex.

https://github.com/shreevatsa/webWEB could be of interest to you.

Happy CWEB programming!
