为什么我的 d3js 饼图中的弧形标签模糊？

Question

I am having a piechart drawn using d3js. to the arc labels i am applying the following style.

.pieChartOuterLabel {
  font-size: 1em;
  fill: black;
  font-weight: bold;
  font-family: 'Times New Roman, Times, serif';
}

this is how my pie chart looks like. you can see the the percentage text labels are blurred ( it seems the other css styles applied to the parent elements are setting opacity to .5 to these labels).

i have tried this but it didnt work well.

.pieChartOuterLabel {
  font-size: 1em;
  fill: black;
  font-weight: bold;
  font-family: 'Times New Roman, Times, serif';
  opacity: 1 !important;
}

the project is available at here . what i expect the arc labels should be displayed in the same style that those in the center text of the doughnut chart.

我通过删除所有<g>元素上的opacity:0.5并使用鼠标事件在弧paths上应用不透明度来修复它，我还将工具提示移高了一点，因为它很难悬停弧线，这是一个有效的stackblitz
