How to draw an Event-sourcing Decider with mermaid.js?

[natalie-o-perret]

I've posted this question on SO, but it hardly gets any answer (none so far), so I thought I might wanna give it a try here:

Long story short, I'm trying to draw this:

with mermaid.js.

My attempts aren't very fruitful:

graph LR
    Command(Command) --> Decide[[Decide]]
    Decide --> Events(NewEvents)
    Events --> Evolve[[Evolve]]
    PreviousState(Previous State) --> Evolve[[Evolve]]
    Evolve --> State(New or Initial State)
    State --> PreviousState
    State --> Decide

gives:

graph LR
    Command(Command) --> Decide[[Decide]]
    Decide --> Events(NewEvents)
    Events --> Evolve[[Evolve]]
    PreviousState(Previous State) --> Evolve[[Evolve]]
    Evolve --> State(New or Initial State)
    State --> PreviousState
    State --> Decide

It looks really off, and I'm wondering how the different elements can be better positioned to look more like the first picture?
