Question

我试图在R中制作Plotly等值区域地图。我在Plotly示例页面中镜像代码如下：

wvs_ag = read.csv("wvs_ag.csv")

l = list(color = toRGB("grey"), width = 0.5)

g = list(
  showframe = FALSE,
  showcoastlines = FALSE,
  showland = TRUE,
  projection = list(type = 'Mercator')
)

p = plot_geo(wvs_ag) %>%
  add_trace(
    z = ~Agree_w, color = ~Agree_w, colors = 'Blues',
    text = ~Country_Code.p, locations = ~Country_Code.p, marker = list(line = l)) %>%
  colorbar(title = 'Agree_w') %>%
  layout(
    title = 'Title',
    geo = g
  )

然而，这会为我生成一张空白地图，只有右侧可见的比例。如何制作地图？

（旁注：我不知道Plotly接受的确切国家代码。我的原始数据有一组国家代码，所以我只是将它与Plotly示例页面中的数据合并，并使用他们的县代码。）
