Pissang and All,
Currently, geo coordinate system only supports GeoJson, which is not
convenient in some scenario that the base map might be the shopping mall
map, airport map, airplane seat map, topographic map, etc., where using
image or SVG is an easy and conventional way.
So, should we provide "echarts option" like the snippet below for this
feature?
```js
var option = {
geo: {
// Use as background image, which can be zoomed and moving in the
geo coordSys.
background: 'shopping-mall.png', // or 'shopping-mall.svg'
// Specify how the background is located in this geo.
// Essentially the value is geo coords of the background rect.
the image width/height, where the geo
backgroundCoord: {
x: 0,
y: 0,
// Conventionally, we can use the image size as the geo coords
here.
width: 1000,
height: 600
},
// In this case, we do not need to provide a GeoJSON and spcify
"mapType" here.
},
...
};
```
In fact, this feature (using a roamable background image on geo) can be
implemented
by the "custom series", but it is not convenient (after all, it require
users to provide a GeoJSON to specify the bounding rect).
Or any other ideas?
