You should share the public held debt percentage of GDP. It still paints a not pretty picture, but doesn't try to go for shock value with a mostly meaningless number/chart.
If US voters were less stupid and less insane, and maybe if there were term limits, maybe this would be addressed someday. For example the Democrats could make changes to Welfare, or the Republicans could make changes to the stupid farm subsidies (like field corn) and oil subsidies, without people having an irrational cow.
