Not able to make it work on Vue3

Hello, I have been trying to make it work on Vue3 without any luck. I feel like I am stuck on something very trivial. Any help would be appreciated. Here is the code. Nothing appears in the ui when I run this except for the background color from the card. There are no errors as well.

<template>
  <v-container fluid>
    <v-row>
      <v-col cols="12">
        <v-card theme="dark" min-height="760">
          <v-card-title>Shapes</v-card-title>
          <v-card-text>
            <div id="canvas"></div>
          </v-card-text>
        </v-card>
      </v-col>
    </v-row>
  </v-container>
</template>

<script>
import Drawflow from "drawflow";
import { h, getCurrentInstance, render } from "vue";
// eslint-disable-next-line no-unused-vars
import styleDrawflow from "drawflow/dist/drawflow.min.css";
const Vue = { version: 3, h, render };

export default {
  name: "CreateFlows",
  data() {
    return {
      shapes: {},
      components: [],
      editor: null,
      dataflowData: {
        drawflow: {

          },

              17: {

            },
          },
        },
      },
    };
  },
  mounted() {
    const id = document.getElementById("canvas");
    const internalInstance = getCurrentInstance();
    this.editor = new Drawflow(
      id,
      Vue,
      internalInstance.appContext.app._context
    );
    this.editor.start();
    this.editor.import(this.dataflowData);
  },
  methods: {},

</script>

<style>
@import "drawflow/dist/drawflow.min.css";
#square {
  background: lightblue;
  width: 100px;
  height: 100px;
}

#triangle {
  width: 0;
  height: 0;
  border-left: 40px solid transparent;
  border-right: 40px solid transparent;
  border-bottom: 80px solid lightblue;
}
</style>

If it is not displayed, it is because you have not defined the height and width in the canvas div. Try adding in the style.

  #canvas { 
    position: relative;
    text-align:initial;
    width: 100%;
    height: 800px;
    border: 1px solid red;
  }
