Inkscape is full of joy! Below are some interesting patterns you can create, and some help on how to learn to master Inkscape with it.
The first point is to use LaTeX with Inkscape. A toolbox interface for that is given by TexText and can help you make graph like that:
How to convert a .png to .svg file with Inkscape: this use case is particularly helpful if you need to create (and guess what you do!) a numeric signature from a scanned version: https://www.youtube.com/watch?v=21S_aGhyDeY see also https://inkscape.org/doc/tutorials/tracing/tutorial-tracing.html.
Weaving Interlacing in vector graphics is useful for making nice pictures often requires manipulating layers in Inkscape. Layers helps creating overlaps, occlusions, etc. (see for instance: https://www.youtube.com/watch?v=3ChqcAdTMAU) and is a key tool for vector graphics, combine with the "fill bounded area" tool.

In connection with Inkscape the software pdftk (on Linux at least) can be used to burst pdfs, or merge pdfs together: see e.g.,
pdftk myfile.pdf burst
or
pdftk *.pdf cat output newfile.pdf
Repeat an Object Around a Shape with Inkscape to get something like pattern_along_path.svg
Challenge: can you replicate this https://ssdesai.wordpress.com/2020/06/30/mandala/ in Inkscape?
