矢印の見た目を変える

• メッセージの消失を示す最後の x を追加
• \ や / を < や > の代わりに使うと
• 矢印の先端が上側だけまたは下側だけになります。
• 矢印の先端を繰り返す (たとえば >> や //) と、矢印の先端が細くなります。
• -- を - の代わりに使うと、矢印が点線になります。
• 矢じりに最後の "O" を追加
• 双方向の矢印を使用する

@startuml Bob ->x Alice Bob -> Alice Bob ->> Alice Bob -\ Alice Bob \\- Alice Bob //-- Alice Bob ->o Alice Bob o\\-- Alice Bob <-> Alice Bob <->o Alice @enduml
