To make Skulpt work with the turtle module it looks for a container of a canvas whose id is “turtle”
Create a CustomComponent and use the html:
<div id="turtle"><canvas width=400 height=400></canvas></div>
But it’s not something we’d recommend implementing apart from toy apps.
Typically if you wanted to use Skulpt to work with turtle, you’d be doing this directly with Skulpt, rather than with Anvil.
