The chart takes the entire range of the data, which in the case of your
population data is 1311-1436, and normalize any value within this range.
So 1311 will get the minimum size, 1436 will get the maximum size, and
anything in between will get a size that is linearly interpolated in this
range. If you want zero to get the minimum size, you can override this by
adding sizeAxis: {minValue: 0} to the options. See the bubble chart options
