{"version":"1.0","type":"rich","title":"Multiple Line plot","description":"This visualization presents a multiple line plot tracking monthly PM2.5 particulate levels in London from 2010 through 2018, with each year rendered as a separate colored line. The chart uses D3 v5 to build SVG paths with a smoothed curve basis, displaying data from the Kings College London Air Quality Dataset. A color legend identifies each year, while the y-axis scale is derived from the 2011 data values. The visualization includes static axes and axis labels, with all nine yearly lines drawn simultaneously on a dark background.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/86772b7b83a143f698bc4d6a2eac91a6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
