{"version":"1.0","type":"rich","title":"PM Emissions in the Metropolitan City of Cagliari","description":"This visualization displays daily average PM 2.5 and PM 10 emissions across multiple monitoring stations in the Metropolitan City of Cagliari. The chart shows time series lines with a dashed World Health Organization threshold line, using a Voronoi overlay via `d3.Delaunay` for hover detection. React manages state for pollutant selection and tooltips, while D3’s `scaleTime`, `scaleLinear`, and `line` handle scaling and path generation. Data comes from a CSV of daily emissions, rendered with SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/852a81195eb84d3a8f946c8bac8995ea?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
