## source
点数据类型,根据经纬点绘制图形,目前支持三种数据结构
- [GeoJOSN]('../source/geojson/#point')
- [CSV]()
- [JSON](../source/json/#点数据)

L7 支持 CSV 以逗号分隔的 CSV 数据加载。
CSV 是文本数据结构,很难表达复杂的地理数据结构,因此 CSV 仅支持两种数据结构
- 点数据 需要指定经度,纬度坐标
- 线段,弧线数据 需要指定 起始点的 经度,纬度坐标
## parser
- type string 必选 json
- x string 点数据表示 经度
- y string 点数据表示 纬度
- x1 string 经度
- x2 string 纬度
### 点数据通过 CSV 加载
```javascript
layer.source(data, {
parser: {
type: 'csv',
x: 'lng',
y: 'lat',
},
});
```
[CSV 数据 demo 示例](../../../examples/point/bubble#scatter)
### 线段弧线数据通过 CSV 加载
```javascript
layer.source(
data,
{
parser:{
type:'csv',
x:'lng1',
y:'lat1' ,
x1:'lng1',
y1:'lat2' ,
}
}
})

GeoJSON 虽然是通用的的地理数据格式,在具体使用场景中,数据服务人员可能并不熟悉 GeoJON,或者没有生成 GeoJON 的工具, 因此 L7 对数据定义了 Parser 的概念,你的数据可以是任何格式,使用指定数据对应的地理信息字段即可。
