{"version":"1.0","type":"rich","title":"Anual AQI (2015) of Tianjin, Shanghai and Guangzhou","description":"This visualization shows the annual Air Quality Index (AQI) for 2015 across three Chinese cities—Tianjin, Shanghai, and Guangzhou—as a streamgraph with wiggling stacked areas. Each city’s monthly AQI values are interpolated to create smooth, colored bands. The visualization uses d3.stack with d3.stackOffsetWiggle and d3.stackOrderInsideOut to generate the layers, and d3.area with d3.curveBasis for rendering. Hovering over a path highlights it in black. The code loads data from a local AQI.json file and employs d3-scaleTime for the x-axis and d3-scaleOrdinal with d3.schemeCategory10 for colors.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7959749d399047849c5bb9456410da2e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
