{"version":"1.0","type":"rich","title":"Indian air quality","description":"This dashboard visualizes air quality trends across Indian states from 1987 to 2015, showing concentrations of pollutants including SO2, NO2, RSPM, SPM, and PM2.5. A dropdown selector displays time-series line charts for each state, while bar charts compare average pollutant levels across all states. The visualization uses D3.js v6 with SVG rendering, employing `d3.rollups` for aggregating state averages, `d3.scaleBand`, `d3.scaleLinear`, and `d3.line` for data encoding, with color mapping via `d3.scaleOrdinal` and `d3.schemeCategory10`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d1e1e6a21db14a5e8447e2711806a460?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
