{"version":"1.0","type":"rich","title":"PM2.5 For Selected Country","description":"This interactive visualization displays PM2.5 air pollution trends for a user-selected country from 2010 to 2017, using data from a Kaggle dataset processed via D3’s `csv` loader. A dropdown menu built with React and D3 lets viewers switch countries, triggering an update that redraws a line chart with `d3.line` and `curveBasis`. The SVG rendering includes axes via `axisBottom` and `axisLeft`, a color legend via `scaleOrdinal` with `schemeCategory10`, and removes and rebuilds all groups on each selection change.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7a5a2a5876a84025860964bd4f188282?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
