PM2.5 Around the World
This choropleth map visualizes global PM2.5 air pollution concentrations for the year 2011, using a grayscale color scale to represent exposure levels across countries. Missing data is marked with a diagonal hash pattern. The visualization uses d3.geoPath with a natural Earth projection, d3.scaleQuantize for color mapping, and d3.zoom for interactive panning. Data comes from a Kaggle dataset processed via TopoJSON and CSV files, with a custom colorLegend component displaying the value ranges for each shade.
AI-generated descriptionA visualization constructed using D3.
The data shown here comes from the Kaggle:PM2.5 Global Air Pollution 2010-2017 (Mean Annual Exposure for 240 Countries) via Gist: PM2.5 Global Air Pollution Dataset (From 2010-2017)
The data is processed and melt to fit the visualization. It realize a Choropleth Map of the world to show the PM2.5 value in a specific year and the distribution around the world.
