Mecklemore Is My Favorite Wrapper
I don't know much about it right now but have you heard of Mapbox? It might be worth a shot, but you did mention leaflet in the next post so I'm not sure because the APIs are similiar. WebMapping seems to be the future for GIS so I'll be learning whatever I can of those while also attempting to learn Web Development.
MapBox is great, with the problem that it's a paid for monthly service that demands you host the data on their own servers. That's a massive no-go in journalism. The data not being wholly yours, that is. I would pay up to a thousand bucks for a program like MapBox that you could then download the tiles and host them yourself. Maybe even more.
