I created a simple mermaid flowchart which displays nicely within zettlr. However, in the eported PDF the mermaid source code is shown, and no flowchart :-(
Anyone experiencing the same problem?
I use zettlr 1.7.5. on IOS.
You'll need a Pandoc filter for Mermaid. Unfortunately, I don't use it and can't recommend anything specific.
I installed mermaid-filter
It uses puppeteer and and should do the trick.
(However, I have some problems on my computer with puppeteer, sigh … )
