Increase the size of all the 'pallozzi', now the color of the smaller one is almost impossible to discern.

More difficult: on roll over on each 'pallozzo' it would be nice to have

• the absolute number of paragraphs
• the value of the deviation rate

Very difficult, as this map has been drawn by hand. We should generate it but we don't have any ready code for that. I think is impossible to include this in the final version.
