Exercise: Originally, the dots in the scatter plot have equal radius. In this task, you will modify the "scatterplot.js" file to encode the values of "sepalWidth" as radius of a scatter plot. Specifically, the radius values for all points should be uniformly scaled within the range [1,10], which means the minimum value of sepalWidth will have radius = 1, and the maximum value of sepalWidth will have radius = 10.
