Take a look at TikZiT, which is a FOSS GUI for creating tikz files and also turning them into image files. I found it really useful for learning TikZ. Note that you don't need TikZiT to generate images, it's just an example of how it's done. Source: over 1 year ago

The best way to TikZ is to copy-paste from previous figures you've created. The second best is to look for a similar figure on TeXample https://texample.net/tikz/examples/ or stack overflow https://tex.stackexchange.com/questions/tagged/tikz-pgf The third best option is to use squared paper to draw by hand, then transfer hand-drawn stuff into TikZ code. It's slow as hell, but works well if you build up a... - Source: Hacker News / about 2 years ago

I suggest you use a gui tool for tikz like Tikzit. Source: over 2 years ago

Would recommend tikzpicture, you can create that sort of diagram and have it written as latex coding to implement in your file. You can create the diagram in TikZit (https://tikzit.github.io) or with MathCha (https://www.mathcha.io). Source: over 2 years ago

Oh, and to easily convert images to ANSI-like art on a modern system, use a program called Playscii (https://jp.itch.io/playscii). Source: about 3 years ago

So I redrew the map of a Sky Tomb from the Stars Without Number adventure Hard Light. They're not spectacular (I'm still new to visual art) but I think they look super cool. I think this visual style fits really well with the OSR. Source: over 3 years ago
