{"version":"1.0","type":"rich","title":"Multiple Line plot with Dropdown","description":"This interactive visualization presents multiple line plots of air quality data from the Kings College London dataset, displayed from January 2010 through August 2018. A dropdown menu allows users to select which pollutant metric to display, with each line colored according to its category. The visualization uses D3 v5 with SVG rendering and animated transitions. The code employs `scaleTime`, `scaleLinear`, `line`, `nest`, and `transition.attrTween` via D3’s transition system, alongside custom modules for the dropdown menu and color legend.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1361ab6ad6e940c5a69d0900c3a0dc59?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
