I don‘t know how to use Czml to create a polygon with complicated interior holes. Does CzmlDataSource support this structure?
Here is sandlink: Cesium Sandcastle

I know czml support polygon with holes。But I just want to know how to write this complicated example with complicated interior holes. I have tried some ,but failed .
some example like this below:
