## 🧹 Data Cleaning Process
- Filtered the full WDI dataset (396,970 rows) down to 8 countries and 6 indicators.
- Identified and backward-filled 3 missing values (Ethiopia's population density, 1990–1992).
- Checked for and confirmed no duplicate country-indicator records.
- Verified column and country name standardization.
- Reshaped data from wide format to long format (1,632 rows) for analysis and dashboarding.
## 🔑 Key Findings
