I've created a map on the CartoDB site and now wish to add some interactivity using CartoDB.js.
I'd like the interactive map to have the same basemap as on the CartoDB site, Nokia Hybrid Day.
The createVis method automatically loads the CartoDB basemap. But I need to use the createLayer method, which does not.
Could you please tell me how I can load the basemap I'm using on the CartoDB site for use with the createLayer method?
