Never mind the ugly website: if you're a programmer tasked with making diagrams, PlantUML is your buddy. You can describe them in editor- and VSC-friendly plaintext like:
```
@startuml
Alice -> Bob: Authentication Request
Bob --> Alice: Authentication Response
Alice -> Bob: Another authentication Request
Alice <-- Bob: another authentication Response
@enduml
```
and let the app render them to a PNG for you.
@ragazzonoioso Oh, cool!
