Compare government balance deficits/surpluses as a percentage of GDP in the U.S., Japan, Germany, and Greece

Please, also explain the graphs as much as possible. Explain the process of searching and selecting relevant data including any difficulties faced, show the charts, discuss their significance, and indicate possible topics for future research.

Ideal would be, if you show the government balance deficits/surpluses as a percentage of GDP first for each country selected and also put them all in one chart, so they can be compared in one chart.

In addition, give a nice short but efficient and easy to understand introduction, where you explain the Topic in order to understand the topic.
