"Partial Graph of the U.S. Income Distribution. The graph represents the population of the United States lined up, left to right, according to income. The height of the graph at any point is the height of a stack of $100 bills equaling that person's income."


"This is a continuation of the previous graph. On the scale of this picture each pixel (dot) represents 250 meters (273 yards), so the football field is invisible. The height of the vertical spike varies from year to year. The height shown represents the increase in Bill Gates' net worth in his best year ($50 billion)".
