Mautic Report for Number of Contacts per Region?

Hello,

Is there a way to create a report that lists the top countries of all contacts with the number of contacts in each? I’d like to be able to funnel down and see a heatmap of where contacts are located as well as have the ability to report the number of contacts in a given region and be able to funnel that down to zip-code ranges.

I tried this with the data source as Contacts and choose country, but the report just gives me an alphabetized list of countries, many that are not related to any contacts.

Thanks,
John Wick
