   • BCreate a histogram of purchase amounts with 10 bins and manually assign customers to segments based on bin ranges.
   • CCreate a scatter chart with purchase amount on the X-axis and visit frequency on the Y-axis, then add a constant line at the average values.
   • DAdd a forecast line to a line chart of total sales over time and use the confidence interval to identify unusual customers.
