1. Regional Sales Analysis
Sales ManagerBackground
A sales manager has a CSV file containing thousands of transaction records across different regions and product lines.
Problem
Needs to quickly see total revenue per product for each region to identify top-performing areas.
How to use
Input the CSV data, set 'region' as the row dimension, 'product' as the column dimension, and 'sales' as the value column with the 'sum' aggregation.
Outcome
A clean, readable table showing total sales figures broken down by region and product, including row and column totals.
