Pie chart in Lumira

Hello,

I'm wonder if I can build pie chart by country, using Lumira from Excel spread sheet in following form:

Country              nb of blogs    nb of discussions     nb of documents

USA                       12                       1                          23

ITALY                      22                      2                          24 

FRANCE                 4                        4                          15

I'm interested in pie chart by country like this:

Is it possible?

thanks
