The SQL project performs a comprehensive analysis of sales transactions by joining three datasets: transactions, customer_list, and customeraddress, to create a unified complete_customer_data table. This table includes details such as customer information, transaction data, and calculated profit (list price minus standard cost). The script then executes various queries to analyze the data, including identifying the top 10 customers by profit, filtering customers with profits above $1,000, determining the most profitable product line, comparing state-wise profits against the average, and calculating each customer's profit percentage. Additionally, it defines a stored procedure to retrieve the top 10 customers by profit and performs temporal analysis to identify customers who made purchases between April and July. Lastly, it compares individual customer profits against state-level profits to gauge their contribution.

The project involves a comprehensive data visualization homework assignment where various chart types are created, including bar, column, histogram, line, area, pie, donut, scatter, bubble, box and whisker, treemap, sunburst, radar, stock, heat map, surface, contour, power map, combo, and sparkline charts. Each chart is designed with specific formatting to align with given examples, showcasing a broad range of data visualization techniques and applications.
