how can I make a simple interactive web map (bigger than what google Chart API allows)

I have a spreadsheet with: URL, 2 digit country code, Main Value, Less important values ...

I just want to make a simple map that can be bigger than what Google Charts API all开发者_如何学Pythonows (that one is limited to 600x600), but a similar level of simplicity.

If it looks nice and is interactive (hovering on country shows data) all the better. If I have to host my own javascript, that's OK.

Maps can be any size you want:

It defaults to the size of the container it is in, so if you put it in a div that is 600x600, it will be that size.
