<script>
  // The library provides a main wrapper component
  // and a bunch empty layout components...
  import { LayerCake, Svg, Html, Canvas } from 'layercake';

  // ...that you fill with your own chart components,
  // that live inside your project and which you
  // can copy and paste from here as starting points.
