@AAMfP because when I looked up how can I insert a diagram in org-mode, #GraphViz seemed simpler to me than #PlantUML, and I sort of got stuck with it. But thank you for the suggestion. @debacle@bbatsov
@RePierre@AAMfP@debacle@bbatsov if I remember right, I just needed to point Emacs to the plantUML JAR and add the language to Babel. Other than me not knowing plantUML, it works pretty well.
