The colors in the pie charts are not my taste, but you can't please everybody's taste. Still I believe that you can improve and make the colors more distinctive.
There are some national preferences: Dutchmen, for example, like orange and they are not amused if orange is taken for Belgians, Germans or Frenchmen. Irishmen are fond of green. Germans don't like to be associated with brown or black...
The percentages would be nice to appear behind the nations' names, like "(L) FIN 31.3%". Hope your software allows for this.

In most countries you find more than 90% bills being issued by this particular country. But the interesting data is which foreign notes you find there. Maybe you just mention the percentage of the original country as a figure and only turn the figures for the other countries into pie slices. In the example of Ireland it would mean that you present the fact that there are 90% Irish bills and that you only put the other 10 countries in a pie chart "foreign notes in Ireland".

yeah, I need to do that. I figured out a way to set the same color in each graph which is an improvement

Humm... I really like that idea. I'm just afraid it might be a bit confusing. How about the general pie chart on the recap page and then what you say on each history page ?
What does everybody think ?

Nice idea, I think (but last word, of couse, is Philippe's).
I propose light blue for Italy (no probs for Frenchmen: their blue is darker)

Well, if you are so much concerned about exact histories, you probably have to present 2 charts:
Chart 1 with the particular nation's bills (90%) and the rest of Europe
Chart 2 with the rest of Europe being split up.
I would not make such an effort, because it also consumes loading time.
As I mentioned before: "90%" plus a pie chart for the rest of Europe would be good enough for me.
For the general pie chart, there is no "rest of Europe" - just keep it as it is.
