{"version":"1.0","type":"rich","title":"PM2.5 Around the World","description":"This interactive visualization displays PM2.5 air pollution levels for countries worldwide from 2010 to 2017. A choropleth map, rendered using d3.geoPath and d3.geoNaturalEarth1, color-codes each country by its annual mean PM2.5 concentration. Users can select a year via a slider, which updates both the map and a line chart showing pollution trends for all countries. Hovering or clicking a country highlights its data in red on the line chart. The data is sourced from Kaggle's PM2.5 Global Air Pollution dataset.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a7f67ce64d59425dbe8c69dae9c2e5d9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
