Deficits as a Percent of GDP--Historical

Quick data note. What do your national (federal) deficits look like charted since 1929, when compared to our GDP? Are they getting better or worse in the last several years? Are they far worse than we have ever seen? I will let the chart speak for itself. The red bars above the 0 line are surpluses--notice there aren't many of these since WWI, so it doesn't seem this has ever been a concern in our history.
