echarts环形图

echarts环形图按照数据显示在整个图表上的占比情况，比如下图所示

代码如下：

let option = {
        title: {
          text: "90%",
          x: "center",
          y: "center",

            fontWeight: "normal",
            color: "#fff",
            fontSize: "20",
          },
        },
        tooltip: {
          formatter: function (params) {
            return params.name + "：" + params.percent + " %";
          },
          show: false,
        },
        legend: {
          show: false,
          itemGap: 12,
          data: ["占比", "剩余"],
        },
