About This Site

Goal:

The information visualization website aims to investigate the relationship between particle pollution and mental depression prevalence across countries worldwide.

Features:

• Interactive global map that allows users to select a world geographic region and filter all the visualizations on the webpage to display data from that region.
• Scatterplot that compares pollution vs. depression, sized based on population or land area, with a best-fit line calculated using linear regression.
• Stacked bars that show pollution levels and depression prevalence on a country level, with darker colors indicating higher pollution and a yellow circle displaying the correlation coefficient value.

Benefits:

By providing users with a range of interactive visualizations, the website enables them to explore and analyze the data in different ways, gain a better understanding of the potential relationship between particle pollution and mental depression, and identify any trends or patterns in the data. The information presented on the website could be valuable for policymakers, researchers, and the public in general, as they seek to better understand and address the impact of air pollution on mental health.

User Interaction:

Users can interact with the website by selecting a world geographic region on the interactive global map, exploring the scatterplot to identify any potential relationships between particle pollution and mental depression, and analyzing the stacked bars to compare the data across different countries. They can also arrange the order of the stack bars based on pollution level or depression level, allowing them to explore the data in different ways and gain a more comprehensive understanding of the potential relationship between particle pollution and mental depression.
