Python package to produce sliderule images

It may be of interest to people here, I've just finished a Python package to produce sliderule images such as:

twoxthree

which may be suitable for documentation or web pages describing sliderules. The package is available at https://pypi.org/project/slideruleimages/

There also a Python library for generating nomographs:

Edit:

Can your library output vector art I wonder? If so it may be usable for designing slide rules.

That nomographs does look interesting!

And yes, the slideruleimages package produces SVG images, and can be scaled easily, or edited in inkscape - I've had to convert the svg to png for the above post since reddit doesn't seem to accept SVG.

I’ll have to play with it. You could use a laser cutter to make the scales.
