Quick Reference Table

Operator	Style	Direction	Use Case
->	Solid	One-way	Sync calls, requests
-->	Dashed	One-way	Async, responses
..	Dotted	None	Weak dependency
<->	Solid	Both	Bidirectional sync
<-->	Dashed	Both	Bidirectional async

Edge Labels

Add context with labels:

[edges]
  api->db:SELECT * FROM users
  api->cache:GET session
  queue-->worker:process
