You're planning to build a tracker for online casinos? Then I don't think it's necessary to make it like a world map.
A map would make more sense for physical casinos because people actually visit those locations. But for online casinos, users don't really care where the casino is physically located since they access it online.
It would probably be more useful to organize them by license, supported countries, restrictions, reputation, and other important details instead.
For me, yeah, a map is cool, but I don't care where the server sits. What I check is the license + if payouts actually happen.
About the Map feature, is this something like an interactive map, like a globe, where you can check a country or location? But I think some crypto casino platforms are just using a virtual office, like paying for some room or address in other countries just to make them look legitimate but they operate worldwide or in a lot of selected countries.
