4. Data Visualization
- Matplotlib & Seaborn – Python libraries for visualizing data.
- Tableau – Drag-and-drop BI and dashboard tool.
- Power BI – Microsoft’s business intelligence platform.
- Plotly – Interactive web-based visualizations in Python or R.
5. Data Storage & Databases
- MySQL / PostgreSQL – Relational database systems.
- MongoDB – NoSQL database for handling unstructured data.
- Hadoop – Distributed file storage for big data.
- Google BigQuery / AWS Redshift – Cloud-based data warehouses.
6. Data Cleaning & Preparation
- OpenRefine – Tool for cleaning messy data.
- DataWrangler – For quick and intuitive data transformation.
- Python Libraries – Like
