🛠️ Tech Stack

This dashboard was built using the following tools and technologies:

• 📊 Power BI Desktop – Main data visualization platform used for report creation
• 📁 Power Query – Data transformation and cleaning layer for reshaping and preparing the API data
• 🧠 DAX (Data Analysis Expressions) – Used for calculated measures, dynamic visuals, and conditional logic
• 🗂️ Data Modeling – Relationships established between tables (weather data, forecast, air quality index) to enable cross-visual analysis
• 📑 File Format – .pbix for development and .png for dashboard preview
