The Problem

Mermaid Code

sequenceDiagram
    actor Customer
    participant ATM
    participant BankServer as "Bank Server / Database"

    Customer ->> ATM: Insert Card
    ATM ->> Customer: Prompt for PIN
    Customer ->> ATM: Enter PIN
    ATM ->> BankServer: Verify PIN
    BankServer -->> ATM: PIN Verified <br>/ Invalid PIN

    ATM ->> Customer: Display Transaction Options
    Customer ->> ATM: Select "Withdraw Cash"
    ATM ->> Customer: Prompt for Amount
    Customer ->> ATM: Enter Amount
    ATM ->> BankServer: Check Balance <br>and Authorize Transaction
    BankServer -->> ATM: Approval <br>/ Insufficient Funds

    ATM ->> ATM: Dispense Cash <br>(if approved)
    ATM ->> Customer: Deliver Cash <br>and Receipt
    ATM ->> BankServer: Update Account Balance
    BankServer -->> ATM: Acknowledgment

    ATM ->> Customer: Eject Card
    Customer -->> ATM: Take Card <br>and Exit

Fixed Mermaid to Excalidraw Output

Fix Summary

• Added <br>/<br/> tag parsing to entityCodesToText function
• Wrap label text with entityCodesToText function
• What the function does?
  • It parses through text labels with <br>/<br/> tags and changes them to " ", a simple space
• Why not a newline?
  • Container boxes for nodes must be added with extra height for the new change in text and the whole excalidraw diagram would have be to readjusted to accommodate such a minor change
• Added test too!

Closes #89
