Final project for Data Analysis Tools class. This project focuses on transforming, analyzing, and visualizing pollution levels of different compounds in Barcelona during 2023, using Open Data Barcelona datasets.

• Collected and cleaned pollution data for multiple compounds (NO2, PM10, O3, etc.).
• Performed exploratory data analysis (EDA) to identify trends and anomalies.
• Created engaging visualizations using ggplot to effectively communicate patterns.
• Applied data transformation and aggregation techniques to prepare datasets for analysis.
• Compiled the results and insights into a PDF report using R Markdown for clear presentation.

• R (ggplot2, dplyr, tidyr, R Markdown)
• Open Data Barcelona as the data source
