{"version":"1.0","type":"rich","title":"Line Chart with Multiple Lines","description":"This line chart displays one week of temperature data for cities worldwide, sourced from Data Canvas - Sense Your City. The visualization uses d3.csv to load the data, d3.scaleTime and d3.scaleLinear for axes, and d3.line with curveBasis to render smooth, semi-transparent temperature trends per city. Colors are assigned via d3.scaleOrdinal with schemeCategory10, and a custom colorLegend module generates the interactive legend. d3.nest groups measurements by city, while axis labels and a title are added as SVG text elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8c6f68ca9515406988cdfaf62549eef4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
