[Vuejs]-Why is Vue-echarts not displaying anything in the DOM?

I found the issue, All I needed was to include the following module:

buildModules: ["@nuxtjs/composition-api/module"]

in my nuxt.config.js file.

My package.json file needed both of the following packages installed as well:

  "devDependencies": {
        "@nuxtjs/composition-api": "^0.29.2",
        "@vue/composition-api": "^1.2.2"
   }

A working version can be found at here.
