custom component

1. echarts example by using vuecharts3

import { contextSymbol } from 'vuecharts3'

const TreemapSunburstTransition = defineComponent({
  name: 'TreemapSunburstTransition',
  inject: [contextSymbol],
  setup() {
    const { chart } = inject(contextSymbol)
    const interval = ref()
    const state = reactive({
      data: null,
      type: '',
    })

    const url = "https://fastly.jsdelivr.net/gh/apache/echarts-website@asf-site/examples/data/asset/data/echarts-package-size.json"
    fetch(url).then(res => res.json()).then(data => {
      state.data = data.children
      console.log('data.value', data.children)
      interval.value = setInterval(function () {
        state.type = state.type == 'treemap' ? 'sunburst' : 'treemap'
        console.log('state.type', state.type)
      }, 3000);
    })
    onUnmounted(() => clearInterval(interval.value))
    return () => state.type == 'treemap' ?
      h(Treemap, {
        id: 'echarts-package-size',
        animationDurationUpdate: 1000,
        roam: false,
        nodeClick: undefined,
        data: state.data,
        universalTransition: true,
        label: {
          show: true
        },
        breadcrumb: {
          show: false
        }
      }) : h(Sunburst, {
        id: 'echarts-package-size',
        radius: ['20%', '90%'],
        animationDurationUpdate: 1000,
        nodeClick: undefined,
        data: state.data,
        universalTransition: true,
        itemStyle: {
          borderWidth: 1,
          borderColor: 'rgba(255,255,255,.5)'
        },
        label: {
          show: false
        }
      })
