US debt visualized
This is exactly the wrong sort of visualization.  It provides no information other than "big number is big, lol."The US debt is a big number.  So big that people have a hard time wrapping their head around it.  They need a point of comparison.  So what's a good point of comparison for the US debt?  Hmm... we could use the federal budget, or GDP, or the world GDP, or the debt of other large nations.  Or we could break it down per capita, and compare it to other per-capita things, like income or tax burden.  Or... I know!  We can convert the thing to hundred dollar bills, and put it next to the statue of liberty!  That's a meaningful comparison!
