{"version":"1.0","type":"rich","title":"PM2.5 For Selected Country","description":"This visualization displays PM2.5 pollution trends for a selected country between 2010 and 2017, using data from Kaggle’s Global Air Pollution dataset. A dropdown menu lets users choose a country, triggering a D3 line chart that updates with the new country’s yearly values. The code uses d3.line, d3.scaleLinear, d3.axisLeft, and d3.axisBottom to render the SVG chart, with a color legend built via a custom colorLegend function. Data is loaded and processed using d3.csv and d3.nest.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6a54d750d4f84b67816bc9e7e6e130ab?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
