Question

我有使用D3和JavaScript创建的地图。我想将西班牙省份的名称翻译成另一种语言，例如英语。默认情况下是西班牙语。我宁愿手动进行这些更改，但是，我不知道应该编辑哪个文件。我尝试编辑hdi.json和provincias.json，但它不起作用（我将省份涂成黑色而没有任何标题，就像它无法识别一样）。任何帮助都非常感谢。

<!DOCTYPE html>
<meta charset="utf-8">
<style>
.nombre{
  stroke: #000;
  stroke-width: 0.5px
}
.graticule {
  fill: none;
  stroke: #777;
  stroke-width: .5px;
  stroke-opacity: .5;
}

.provinceNames
{
  font-size: 0.9em;
  font-family: "Lato";
}

.legendLinear
 {
  font-family: "Lato";
  fill:#000000;
}

.legendTitle {
  font-size: 1em;
}
#tooltip {
  position: absolute;
  top: 0;
  left: 0;
  z-index: 10;
  margin: 0;
  padding: 10px;
  width: 200px;

您似乎正在将this JSON用于西班牙各省。

如果这是正确的，该文件是“provincias.json”，这是名称的路径：

provincias.objects.provincias.geometries[index].properties.nombre

index是geometries数组中所需的索引。

查看此演示：

d3.json("https://cdn.rawgit.com/rveciana/5919944/raw//provincias.json", function(provincias) {
  provincias.objects.provincias.geometries.forEach(function(d) {
    console.log(d.properties.nombre)
  })
})

<script src="https://d3js.org/d3.v4.min.js"></script>

如何更改地图上各省的名称？
