Generation of Multi-Dimensional Content Slots to Increase Display Availability of User Interfaces

Example embodiments of the present disclosure provide for an example method that includes obtaining data indicative of a user initiating a map application instance on a client device. The method includes determining multi-dimensional geographic content slots for content items to populate by determining geographic boundaries associated with geographic areas. The method includes generating a shape that aligns with the geographic boundaries and generating a multi-dimensional content item slot that aligns with the shape that aligns with the geographic boundary. The method includes determining a content item to populate within the multi-dimensional geographic content slot. The method includes providing the content item to the client device to be displayed within the multi-dimensional geographic content slot in the user interface of the client device associated with the map application instance.
