Yes it does, while also very much being of the do-one-job-well philosophy. 
Not surprising from something Brian Kernighan wrote.

Is Pitchr available as a executable somewhere? All I could find was the C

No, Pikchr is not currently available as an executable. However pretty much 
any C build environment will create an executable as follows.

1. Get the (very small, zero dependency) Pikchr source from one of:
    a) https://pikchr.org/home/download . This is an automatic 
tarball/zip/sqlar from the latest Fossil checkin.
    b) the command "fossil clone https://pikchr.org/"

2. cd pikchr
    make

   this will give you a binary called "pikchr" (probably PIKCHR.EXE for 
Windows, but I have never tried with Windows)

3. You can then try pikchr:

./pikchr --svg-only examples/headings01.pikchr

will produce only the SVG code corresponding to the Pikchr code. 

 ./pikchr examples/headings01.pikchr > /tmp/headings.html

This wraps the SVG in HTML, you can point your web browser at 
/tmp/headings.html

I have an SVG convertor called rsvg-convert from the librsvg2-bin package. 
Using this I can generate PNG:

./pikchr --svg-only examples/headings01.pikchr | rsvg-convert > 
/tmp/headings.png
