The nice folk at translation website bab.la have created a "world languages map", showing the most-spoken first languages on each continent.
Here's the map in its online, interactive form. Zoom in or out using your mouse wheel:
If you would like a free copy of the map in poster form, visit the 'world languages' page of the bab.la website.
Should you have any problems requesting your poster from bab.la, let me know (via email) as I have a spare copy and am more than happy to send it on to anyone who wants it.
Bab.la also has a blog, Lexiophiles, which is worth checking out.
