Bubble cart is not showing any data in sap overview page

Hi Experts,

I am creating a sap overview page with bubble cart, but I am not able to show any data in that cart.

Please help.

  "settings": {

  "title": "Meet Our Staffs!",

  "category": "NorthWind Company",

  "chartAnnotationPath": "com.sap.vocabularies.UI.v1.Chart#SalesTotalsbyAmount",

  "dataPointAnnotationPath": "com.sap.vocabularies.UI.v1.DataPoint#SalesTotalsbyAmount"

  }

  }
