PM2.5 New York's Summer vs Winter

when do we need a N95 mask to prevent PM2.5?

Overall, we can see the air quality is better during the wimter. However, we might need a N95 to prevent PM2.5 in summer.

Design Specification:

I use Quicksand font to reflect the particle form. And bluish color tone to represent the sense of air. For the dataset, I only use the "Fine Particulate Matter (PM2.5)" value in the downloaded CSV and compare the mean for winter and summer. To provide better understanding of the concept, I will add the text "Summer" in the tooltip when hovering instead of years.
