Add a "no tiles" option

See #249.

Simple, clean. Thanks @ocefpaf .

I am not sure if we can change the grey background to another color though. But this will be a niche feature anyways.

An ugly hack: if you want a white background, you can create a Layer pointing to white tiles.

# Create a white image of 4 pixels, and embed it in a url.
white_tile = folium.utilities.image_to_url([[1,1],[1,1]])

# Create a map using this url for each tile.
m = folium.Map(tiles=white_tile, attr='white tile')

I don't think it shall be embeded in folium, but it's good to remember.

Agree.

but it's good to remember.

👍 (That actually gave me a few crazy ideas 😉)

Yeah ; like:

tile = folium.utilities.image_to_url([[(-1)**((i+j)//30) for i in range(300)] for j in range(300)])
tile = folium.utilities.image_to_url([[(-1)**((i//30+j//30)) for i in range(300)] for j in range(300)])

I really like the second one:
