Using HTMLCanvas element how to draw line with specific condition in Vuejs?

var example1 = new Vue({
  el: '#example-1',
  data: {
    questions: [{
        id: '1',
        message: '1',
        checked: false,
        statuses: ['match', 'closeTo', 'veryfar']
      },
      {
        id: '2',
        message: '2',
        checked: false,
        statuses: ['match', 'closeTo', 'veryfar']
      },
      {
        id: '3',
        message: '3',
        checked: false,
        statuses: ['match', 'closeTo', 'veryfar']

Logic I am trying to achieve :- https://stackblitz.com/edit/vue-laepf5

Using above provided logic in “stackblitz”. I am trying to write logic into two components and achieve the same functionality. During that process, i am facing multiple issues like,

[Vue warn]: Error in v-on handler: “TypeError: fromEl.getBoundingClientRect is not a function”
TypeError: fromEl.getBoundingClientRect is not a function

Codesandbox link, Where trying to split logic in two components.
