Today I have discovered #emacs #orgroam in more depth.
Visualization to build a kind of #knowledgegraph with #orgroamui is really impressive. I am curious about the knowledge I gain when the number of nodes (less than 50 now) becomes larger.
For more graphics I will try out @igraph in #R. Perhaps it is possible to show node connections based on tags.

@sqrtminusone I use #emacs on #termux , too. #SamsungDex makes it even more pleasant when you use #OrgRoamUI.
