I have an echarts map already, see the image.
I use echarts.registerMap() with some geojson data. Those are they grey polygons shown in the image.
Data Series are the green and black polygons
Now I want to add a streets layer on the background.
Using Google, Baidu or similar is not an option.
Streets layer already exists in a Geoserver accesible to me.
Geoserver can provide a wms layer.
How can I insert this wms layer in the echarts background ??
Is it possible ??
Thanks in advance
