This one is called: "Birth Weight". This chart accounted for approximately 200 babies, and concluded that my friends tend to have pretty big babies. The U.S. average is 7 pounds 8 ounces, and 71% of my facebook friends had babies that weighed more than that (our average was 8 pounds 1 ounce).
And here's just a shot of that same chart, except removing the pre-term babies, and it's called: "Birth Weight and Gestation of Full-Term Babies":
That's all of the charts I've done so far. They've proven to be quite popular on my facebook page. A lot of people respond to them, and people have offered suggestions of what they want to see next, so there will probably be more done in the future.
