Chidi's investor presentation needs a customer growth chart. A PivotChart showing monthly customer acquisition will be the centrepiece of the customer slide.

In Meridian_Data.xlsx, create a PivotTable in a new sheet called Customer Growth using the Customers sheet. Group by acquisition month. Show count of non-duplicate customers acquired each month. Add a running cumulative total column next to the PivotTable using a formula. Build a combination chart: bars for monthly new customers, line for cumulative total. Format with Meridian brand colours — orange bars, navy line.
