All children components of a <constrainedlayout /> will be automatically laid out by solving for all the <constraint />s that are defined within the <constrainedlayout />.

export const MyCircuit = () => (
  <constrainedlayout>
    <resistor name="R1" resistance="1k" footprint="0402" />
    <resistor name="R2" resistance="1k" footprint="0402" />
    <constraint pcb xdist="10mm" left=".R1" right=".R2" />
  </constrainedlayout>
