maptalks 繪製熱力圖

1. 安裝maptalks.heatmap插件

   	yarn add maptalks.heatmap --save
   

2. 在頁面import相關組件

       import MaptalksCom from '@components/mapComponents/MaptalksCom'
       import { HeatLayer } from 'maptalks.heatmap'
   

3. 準備數據，構建heatLayer，添加到map對象中

   	const addressPoints = [
       [-37.8839, 175.3745188667, "571"],
       [-37.8869090667, 175.3657417333, "486"],
       [-37.8894207167, 175.4015351167, "807"],
       [-37.8927369333, 175.4087452333, "899"]]
       const heatlayer = new maptalks.HeatLayer('heat', data, {
           'heatValueScale': 0.7,
           'forceRenderOnRotating' : true,
           'forceRenderOnMoving' : true
       }).addTo(map);
