Can I create start point?

I'm trying to create a diagram for my project with d2 and I want to create a starting point, but I don't understand how to do it.

Like this ?

classes: {
init: {
label: ""
shape: circle
style.filled: true
style.fill: "#0D32B2"
style.stroke-width: 0
width: 15
}
}

init.class: init
init -> Locked
Locked -> Locked: Push
Locked -> Unlocked: Coin
Unlocked -> Unlocked: Coin
Unlocked -> Locked: Push
