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

And then you can perform further edits using something like https://asciiflow.com/ (web, free) or https://ivanceras.github.io/bob-editor/ (web, free) or https://monodraw.helftone.com/ (Mac only, proprietary) as mentioned in other comments from https://news.ycombinator.com/item?id=37040883. - Source: Hacker News / 9 months ago

Typograms could be great with the monodraw app on macOS. I'm a very happy customer of monodraw-- not affiliated in any way. https://monodraw.helftone.com/. - Source: Hacker News / 10 months ago

Admittedly, creating that asciiart by hand is obnoxious, but tools like monodrow https://monodraw.helftone.com/ make it easy. However, then we're right back at the question of why bother using markdown if you're making complicated graphics in another tool anyway. I love Monodraw and use it for many things (it can create svg and png and other formats not just ascii) but yeah, it doesn't seem like a great solution... - Source: Hacker News / over 1 year ago

I’ve been using MonoDraw https://monodraw.helftone.com/ for this exact sort of stuff for years, was one of the main reasons I bought the program actually. A good diagram in a block comment right above or below done complicated code is a ready powerful way to make sure you’re going to be able to maintain that code in the future. I find flowchart style diagrams for finite state machines and UML(ish) sequence... - Source: Hacker News / over 1 year ago

The given URL is about what's new in 1.6 and mostly boils down to: * "app icon, document icon and welcome window", * "ability to simultaneously edit multiple shapes of the same type", * "minimum OS requirement has been raised to macOS 11 Big Sur".
