A histogram would be appropriate for this distribution since it is a continuous variable (weights) that can be grouped into intervals (age groups). A pie chart would not be appropriate since there are no categories to compare and a scatter plot would not be appropriate since there is no correlation being examined. A bar graph could work, but a histogram would display the continuous nature of the variable better.
