"aggregate": "sum",
"type": "nominal"
}

}
}

Hey @suibgui!

From the config you posted, I don't see anything immediately wrong but if you haven't seen, maybe comparing with our guide can help you get something working. https://www.elastic.co/guide/en/kibana/current/vega-lite-tutorial.html

Also covered in that guide are some debugging steps so hopefully those can help get your visualization working!
