interactive world map for contacts

It would be helpful and insightful if Hubspot had a flexible, interactive world map tool based on contact location information, which could also include properties so that you can zoom in, click, see # of subscribers, # of unsubscribers, and # of neither, to quickly identify different targeting possibilities.
We offer many in-person events around the world and it currently takes a lot of time and quite a manual lift to build a targeted email audience list for each event location since it will depend on event location and what profile information the user has provided, if they are subscribed or not, etc.
A quick interactive map tool would be super helpful for quick insights.
