I've tried so many of these diagramming tools (mermaid, draw.io, figma, lucid chart). But none of them seem to ever match the effectiveness and simplicity of PowerPoint. Why reinvent the wheel so many times?
Some of the reasons why an application developer might prefer using Diagram Maker over using draw.io's embed mode in their application: * You want to customize the editor to match your application's styling. * You want the editor to impose your application's custom semantics, for example: your application doesn't allow cycles.
If PowerPoint works for you, that's great! I have no problem with it. But it doesn't work for me. There is a true need in this area for better diagramming tools. Plantuml and graphviz were good ideas, for which we still lack a killer execution/implementation.
I use a mac and am not a big fan of opening up office products for simple/quick things
