All the numbers should already be formatted according to the locale of the reader (defined in their browser), except for the home plot's X axis, which is eluding my best efforts so far. I tweaked it a little (will be published with the next batch) but I can't manage to get it to print the , for thousands using the same formatter as the others, when the browser is set to english, nor the spaces when it's in french.

I think we just need a . not a , .
