Project: sales dashboard with pandas and matplotlib

Turn a year of order lines into a sales dashboard: monthly revenue, top products, regional comparison, two charts and a KPI summary, all built as small tested functions.

You will be able to

• Load a CSV with pandas, parse dates and derive a revenue column
• Group and pivot order data to answer specific business questions
• Rank results deterministically, including ties
• Build charts in functions that return their Axes so they can be checked automatically
• Combine the analysis into a KPI summary and handle empty or one-month data
