Congratulations! You've completed **Phase 3: Visualization & EDA**. You can now paint with data.

Today, we're building an **Annual Review Report**.

The Scenario

Your company has had a wild year. You need to show:

1. **The Trend**: A Line chart of monthly revenue.

2. **The Success**: A Bar chart of our top 5 products.

3. **The Problem**: A Box Plot of shipping times (to find why customers are complaining).

4. **The Correlation**: A Heatmap of website features vs spent money.

The Professional Requirement

  • Use professional colors.
  • Use subplots to keep it neat.
  • Add annotations to major spikes in the data.

    • What you've achieved

    You've matured from someone who "Calculates" to someone who "Communicates." You've earned the trust of stakeholders by making data readable and persuasive.

    **Phase 4 (Days 141–150): Machine Learning Intro**. This is the future. We're going to teach your computer how to see patterns on its own.

    See you in the final phase!
