Project: Data Analysis and Visualization

Learning Objectives: Apply everything you've learned in a comprehensive project that analyzes and visualizes real data. You'll use variables, data structures, functions, OOP, error handling, and create interactive visualizations.

Project Overview

In this capstone project, you'll build a Sales Data Analysis System that:

• Loads and processes sales data
• Performs statistical analysis
• Creates interactive visualizations
• Handles errors gracefully
• Uses object-oriented design
• Provides a user-friendly interface

This project combines all the Python fundamentals you've learned throughout the course.

Project Architecture

Let's start by designing our system using OOP principles:

Step 1: Data Loading and Validation

Step 2: Data Processing and Analysis

Step 3: Data Visualization

Step 4: Interactive Visualizations

Now let's explore our sales data with an interactive visualization dashboard:

Step 5: Complete System Integration
