Hi Maintainers ,

I'm excited to submit this PR that adds an interactive dashboard example built using Preswald! 🚀
This demo showcases how users can quickly set up a data dashboard using simple configuration, CSV data, and visuals — aimed to help new users get started faster.

✅ What's included:

• A minimal hello.py script
• Sample preswald.toml configuration
• Sample dataset (sample.csv)
• Basic branding (favicon, logo)
• Secure settings via secrets.toml

Please feel free to review and share any feedback — I’d be happy to make any improvements or changes as needed

Thanks for this awesome project and opportunity to contribute!
– Sagar
