I have been using Emacs for about 4+ years now, and I still find new things.

One of the thing I discovered this week is ability to create mindmaps without leaving the comfort of Emacs 😄 This is made possible via PlantUML.

Doom emacs makes it very easy to set it up.

1. Enable plantuml in the init.el of your doom emacs config.
2. M-x doom/reload (This will install the appropriate packages)
3. M-x plantuml-download-jar (Make sure you have working java installation)
4. doom/open-scratch-buffer
5. org-mode (Not sure if this is needed, but better be explicit)

Now create following in your scratch buffer that is already in plantuml mode.
