Your English is better than my Spanish :-)
If you keep noodling on this then I'd suggest getting the nuclear stack down pat, then gradually integrating full energy mixes per country, at first just showing the proportions of energy use provided by nuclear.
Make things clear as you go - a countries energy use is more than just electricity generation, for example, aim for bright 15 years old as a target audience perhaps.
A good many people do want to see better "dashboards" for their planet, over all and country by country.
thanks! and your comments are in the right direction, I plan to integrate other layers of the global energy network, with a better visualization of nuclear proportion by region/country.
