Apache echart Json Data contains spend in place of value

Question

Hi I am using apache echart so for the i have created the used the example script

option = {
  tooltip: {
    trigger: 'item'
  },
  legend: {
    top: '5%',
    left: 'center'
  },
  series: [
    {
      name: 'Access From',
      type: 'pie',
      radius: ['40%', '70%'],
      avoidLabelOverlap: false,
      label: {
        show: false,
        position: 'center'
      },
      emphasis: {
        label: {
          show: true,
          fontSize: 40,
          fontWeight: 'bold'
        }
      },
      labelLine: {
        show: false
      },
      data: [
       {name: 'test1', spend1: 12468.31},
       {name: 'test2', spend2: 2322}
      ]
      
    }
  ]
};

In this case labels are visible test 1 and test2 but piechart is not visible . I am new to this can anyone help me how can recplace spend 1 AND spend2 with value.

Solution for my json data so that pie chart will be visible
