PM 2.5 2018 in US
A scatterplot displays PM2.5 air quality levels for U.S. counties in 2018, with each circle plotted by county FIPS code on the x-axis and annual PM2.5 concentration on the y-axis. The visualization reveals that Alaska and Wyoming have the cleanest air, while California suffers the worst due to wildfires. Built with d3.v5 and the vega-lite-api, it loads CSV data, uses vega-lite’s markCircle encoding, and applies a custom configuration for improved readability.
