Add "Tutorials" folder for comprehensive learning resources

[Leo-bsb]

Summary

I'd like to propose adding a "Tutorials" folder to complement the existing "Examples" folder. While examples are great for quick reference, tutorials would provide step-by-step learning content for new users.

Motivation

• Current examples are concise and focused (great for reference)
• New users would benefit from comprehensive, educational content
• Tutorials could showcase real-world use cases and best practices

Proposed Structure

pygwalker/
├── examples/ # Existing - short scripts
└── tutorials/ # NEW - comprehensive guides
├── README.md
└── complete_tutorial.ipynb

First Contribution

I've created a comprehensive tutorial notebook covering:

• Setup and basic usage
• All chart types and features
• Real-world use cases (sales analysis, customer segmentation, A/B testing)
• Performance optimization and best practices

Preview: Google Colab Notebook

Duration: ~30-45 minutes
Level: Beginner to Intermediate

Questions

1. Does this align with the project's documentation goals?
2. Would you accept a PR adding this tutorial?
3. Any preferences for structure or format?

I'm happy to adjust based on feedback. Thanks for considering!

This is a fantastic tutorial — it’ll be super helpful for many PyGWalker users.
Thanks for the great work! We’d be happy to review a PR including your tutorial.

A small requirement to check before submitting:

• Please ensure the .ipynb file does not include cell outputs. PyGWalker outputs often embed large HTML snippets, which can unnecessarily bloat the commit history.

Looking forward to your contribution!

Hi @ObservedObserver,

Thanks so much for the positive feedback and the heads-up about outputs! I’ve ensured the notebook is clean of outputs and just submitted the PR #721.

Please let me know if there’s anything else I should adjust. Looking forward to your review!
