       | To be honest, diagram-as-code is so powerful I can't be tempted
       | by eye-candy. What is the game changer with C4 and all its
       | editors (if more than this)?

         | 
         | The actual standard is quite light weight, which is its main
         | selling point. The whole premise is that many teams find
         | rigorous standards like UML and Archimate too heavy and thus
         | resort to basic boxes-and-lines diagrams. C4 essentially says
         | "take your boxes-and-lines and put full sentence descriptions
         | on everything". Combine that will successive levels of detail,
         | and you have the C4 standard.
         | 
         | You don't have to give up diagrams-as-code because you can
         | create C4 diagrams with PlantUML [0] or using the C4 specific
         | DSL [1].

         | C4 model creator here ... in a nutshell, the C4 model is: 1. a
         | hierarchical set of abstractions to describe software systems,
         | and 2. a hierarchical set of diagrams to visualise those
         | abstractions. Benefits include it providing teams with a
         | lightweight common vocabulary to describe/visualise software
         | architecture, with the resulting diagrams being "developer-
         | friendly". It's also independent of any specific notation and
         | tooling. My top tip is that you don't need to use all four
         | levels ... the first two are usually sufficient for most teams.
         | 
         | I agree, diagrams as code is very powerful, and that would be
         | my recommendation for teams looking for tooling ... the
         | Structurizr DSL being the tooling that I created specifically
         | to create multiple diagrams based upon the C4 model, in
         | multiple output formats, from a single DSL source file. You can
         | see a demo at https://structurizr.com/dsl and there are more
         | details at https://structurizr.org
         | 
         | Some teams do like the familiarity of diagramming/modelling via
         | a UI though, and that's where something like IcePanel fits in.

         | DAC has a lot of strengths for technical users and audiences,
         | but it isn't accessible for everyone. Our focus is keeping
         | everyone in the team up to date and on the same page about the
         | system design and in line documentation in an accessible,
         | simple way. Decisions get made all the time and (most) often
         | aren't captured in places everyone can access. Simply
         | understanding how the product works that you're involved with
         | shouldn't be difficult. There is a table for comparison here:

           | I don't understand, though. Since it's a model, why say
           | "gitable=no" instead of having ability to have those "frozen
           | sources of truth" git-committed?
           | 
           | In fact, it's not clear to me, can I even get the model code
           | out of this? I see "model export" but can't tell what the
           | toolbox means from your visual tool.
           | 
           | I _really_ want to use this, but only if it integrates back
           | into the everything-as-code record. (I don 't even care if
           | bi-directional for now, but it has to snapshot the model
           | out.)

             | What use cases do you have that need the model to be
             | committed to the repository if it wasn't bi-directional?

         | 
         | It can then create multiple views. For instance focus on one
         | component and filter which relationships to show.
         | 
         | I end up with 8 or more views, a few of which are useful to
         | highlight a problem or problematic dependency.
         | 
         | It can export plantUML as well as SVG.
         | 
         | plantUML is more open and more widely applicable. C4 is a
         | process of cataloging.
