## 图表类型：地理坐标系上的等值区划图和散点图 (Geo Choropleth and Scatter)

**生成指令**：你现在的任务是生成一个 ECharts 的 `option` 配置。请根据以下骨架代码和数据结构要求，结合用户的实际数据进行填充和修改，生成一份完整的图表配置参数。

### 外部数据结构分析
该图表需要特定的外部数据结构支撑。以下是下载后的数据结构示例，请将用户的真实数据映射为类似结构：

**数据文件 [/data/asset/geo/iceland.geo.json]**:
```json
数据是一个对象 (Object)。包含的顶层字段示例：type, features。数据截取示例：
{
  "type": "FeatureCollection",
  "features": [
    {
      "type": "Feature",
      "geometry": {
        "type": "Polygon",
        "coordinates": [
          [
            [
              -14.6146,
              65.9863
            ],
            [
              -14.663,
              65.9811
            ],
            [
              -14.6941,
              65.9438
            ],
            [
              -15.1014,
              65.922
            ],
            [
              -15.1263,
...
```

### ECharts Option 骨架参考
请基于此结构（已剥离冗长写死的数据）生成配置。不要直接输出此骨架，而是要输出**包含真实数据和完整逻辑**的完整 `option` 对象：

```javascript
function createChart() {
  var icelandRoughLatitude = 65;
  option = {
    geo: {
      map: 'iceland',
      roam: true,
      aspectScale: Math.cos((icelandRoughLatitude * Math.PI) / 180),
      // nameProperty: 'name_en', // If using en name.
      label: {
        show: true,
        color: '#555'
      }
    },
    tooltip: {},
    visualMap: [
      {
        orient: 'horizontal',
        calculable: true,
        right: 0,
        bottom: 0,
        seriesIndex: 0,
        // min/max is specified as series.data value extent.
        min: 0,
        max: 1e5,
        dimension: 2,
        inRange: {
          symbolSize: [5, 30]
        },
        controller: {

        type: 'map',

        // instead of creating an internal geo coord sys.
        geoIndex: 0,
        map: '',
