> Typograms optimizes for editability and portability (e.g. plain text is easy to maintain, change, store and transmit), at the cost of expressivity (e.g. SVG is more expressive) and ergonomics (e.g. higher level tools produce diagrams faster).

How can it be both “easy to change” and not be ergonomic?

[kazinator]

Because the editing is at the character level.

If you look at the page source, this is what the grids look like for instance:

    +----+        +----+                                                                                                         
   /      \      /      \            .-----+-----+-----.                                                                         
  +        +----+        +----+      |     |     |     |          .-----+-----+-----+-----+                                      
   \      /      \      /      \     |     |     |     |         /     /     /     /     /                                       
    +----+        +----+        +    +-----+-----+-----+        +-----+-----+-----+-----+                                        
   /      \      /      \      /     |     |     |     |       /     /     /     /     /
  +        +----+        +----+      |     |     |     |      +-----+-----+-----+-----+
   \      /      \      /      \     +-----+-----+-----+     /     /     /     /     /
    +----+        +----+        +    |     |     |     |    +-----+-----+-----+-----+
          \      /      \      /     |     |     |     |   /     /     /     /     /
           +----+        +----+      '-----+-----+-----'  '-----+-----+-----+-----+

That's easy to change, but even for the top Vim slingers, it's not that ergonomic to produce by text editing.

You could benefit from tooling to produce the underlying ASCII diagrams; this tool is just a renderer to make them look nicer.

Exactly.
