Plotly always crashes

[CreativeStoic]

This code:

const datas: Datas<"Plotly"> = { data: [{ x: [0], y: [0], type: "bar" }] };
  new Deplot("Plotly", {
    title: "Proportion of Bugs by Month",
    size: { width: 800, height: 600 },
  }).plot(datas);

When executed with this command:
deno run --allow-env --allow-net --allow-read --allow-write --allow-ffi main.ts
Results in this error:

error: Uncaught (in promise) TypeError: Deno.dlopen is not a function
  return Deno.dlopen(
