{"version":"1.0","type":"rich","title":"PM2.5 For Selected Country","description":"This visualization displays PM2.5 air pollution trends for a selected country from 2010 to 2017 using a multi-line chart. A dropdown menu allows users to switch between countries, updating the line path to show that nation’s annual mean exposure values. The code uses D3 v5 with React, employing `d3.line`, `d3.scaleLinear`, `d3.axisLeft`, `d3.axisBottom`, and `d3.nest` to process and render the data. It also uses a custom `colorLegend` component and `foreignObject` for the dropdown UI. Data originates from a Kaggle dataset loaded via a Gist URL.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c489a83c30fe4d9db1e881d180aa6ec4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
