如何将 geojson 数据添加到 react-map-gl 的 Source 和 Layer Component

Question

我正在使用 react-map-gl 库来处理 mapbox。我想在地图上的某些数据点上创建一条线。地图渲染良好，但地图上未显示线条。

坐标应为 LineString 的二维数组。

dataJS 应该是这样的

const dataJS = {
  type: "Feature",
  properties: {},
  geometry: {
    type: "LineString",
    coordinates: [
      [-67.13734351262877, 45.137451890638886],
      [-66.96466, 44.8097],
      [-68.03252, 44.3252],
      [-69.06, 43.98],
      [-70.11617, 43.68405],
      [-70.64573401557249, 43.090083319667144],
      [-70.75102474636725, 43.08003225358635],
      [-70.79761105007827, 43.21973948828747],
