Interactive Map

hi guys,

I’m looking for an interactive world map that allowds me to connect each locations with all the posts about that locations.
I am working on a touristic/traveller website.

For example let’s say I have 10 posts regarding London, and each of them is under a different category. If I add London as a location on my map everyone interested in London should click on the pin and have an overview on what posts are about London.

Is there any plugins or widgets I can download??

Thanks
