How to optimize the layout of this state diagram? The default state diagram is too ugly

Question

code:

@startuml

[*]--> BusSleepMode :power on

BusSleepMode -up->[*] : power off

state NetworkMode {

    [*] --> ReaptMssageState

    ReaptMssageState -down-> NormalOperationState

    ReaptMssageState -down-> ReadySleepState

    NormalOperationState -right-> ReadySleepState

    ReadySleepState -left-> NormalOperationState

    ReadySleepState : Stop Nm message 

} 

BusSleepMode -down-> NetworkMode

PrepareSleepMode -left-> BusSleepMode

ReadySleepState -up-> PrepareSleepMode

NetworkMode --> NetworkMode

PrepareSleepMode -down-> ReaptMssageState

Answer 1

If you add an extra rank depth between "PrepareSleepMode" and "ReaptMssageState" then you get slightly closer to your expected diagram.

PrepareSleepMode --down-> ReaptMssageState

Using the <<end>> stereotype, you can have the middle dots of your expected diagram.  For some reason there is no <<start>> stereotype to get the fully black dot.
