This project is a beginner-to-intermediate level data analysis of sales data using pandas, NumPy, and Matplotlib. It demonstrates how to read, clean, analyze, and visualize sales information from a CSV file.
sales2_1.csv: The dataset.sales2.py: Main Python script that processes and visualizes the data.revenue_profit_chart.png: Output chart showing revenue per product.
- Convert raw sales data into useful insights.
- Calculate total revenue per product.
- Use NumPy for array manipulation and slicing.
- Visualize results with a colorful, labeled bar chart.
The dataset contains the following columns:
- Product: The name of the product.
- Quantity: Units sold.
- Price: Unit price in dollars.
- Date: Date of sale.
- Read CSV Data using
pandas. - Convert Columns to Numeric types with error handling.
- Calculate Revenue per row (Price ×ばつ Quantity).
- Convert DataFrame to NumPy Array for slicing and filtering.
- Extract Unique Products and compute:
- Total revenue per product.
- Percentage share of total revenue.
- Visualize the Results using
Matplotlib:- Each product is assigned a unique color.
- Products are displayed as numbered bars.
- A dynamic legend explains which number corresponds to which product.
