Region Map on Kibana Vega

Hello,

I work on a map in Vega in Kibana (the map of kibana config=map), and I plot some positions with the projection:"projection".
I wan't to add areas to show on the map, like timezones. Similar to the region map visualization in Kibana. Moreover Kibana knows information like countries (like in https://maps.elastic.co/#file/world_countries) .
So, how can I add areas?
I've tried used TopoJSON but it use width and heigth, but kibana map doesn't use that.

Thank you in advance.

Wait, so you're using Vega, not the Maps application? I would think this would be easier to accomplish there if you can switch to it.

I can't use the Map application because I want Region Map and Coordinate Map at same time.

But finally, I succeed using this tutorial (https://vega.github.io/vega/tutorials/airports/) , and drawing boundaries like for the states in the US with a geojson file of the timezones in the tuto. You just need to use the projection automatically created by kibana named "projection" instead of defining a custom one.

Thank you.
