Refactor Streamlit App for Better Performance and Maintainability

[say-het]

Describe the bug
The current Streamlit app implementation can be optimized for better performance, readability, and maintainability. The code contains repetitive elements and lacks modularity. This issue aims to refactor the codebase to address these concerns.

Proposed Changes:

Modularize Code: Break down the code into smaller, reusable functions.
Refactor Repetitive Code: Use functions to handle repetitive tasks.
Improve Readability: Add comments and organize the code into logical sections.
Dynamic Data Loading: Load data based on the selected year to optimize performance.
Enhance Visuals: Use consistent formatting and better layout management.
Add Error Handling: Ensure the code handles potential errors gracefully.

Steps to Implement:

Define functions for loading data, applying CSS, displaying analysis text, and visualizations.
Refactor the main script to use these functions.
Test the refactored code to ensure functionality remains intact.
Review and update documentation/comments for clarity.

Benefits:

Improved performance by dynamically loading data.
Enhanced code readability and maintainability.
Simplified future development and feature additions.
