Data Cleaning/Visualization

Using SQL & Tableau to Prepare Data and Visualize Findings.

It’s been a while since I’ve worked on a personal project using Tableau and SQL, but I finally had a chance to dive back in with a dataset that caught my interest: Airbnb listings across New York City’s four major boroughs.

Using SQL to clean and explore the data, I built a Tableau dashboard to visualize key insights, including:

  1. The number of listings per borough

  2. The highest and lowest Airbnb prices by borough

  3. The top 5 and lowest 5 rated listings based on star ratings

It was a great way to practice combining SQL and Tableau while uncovering interesting patterns in NYC’s short-term rental market. I’m excited to share the dashboard and insights from this project, and I look forward to continuing to explore real-world datasets in creative ways.

Software used: SQL, DuckDB, DBeaver, Tableau Desktop
