{"version":"1.0","type":"rich","title":"Line Chart with Multiple Lines","description":"This line chart displays one week of temperature data from multiple cities, sourced from Data Canvas - Sense Your City. A d3.nest() groups the data by city, with d3.scaleTime() and d3.scaleLinear() mapping time and temperature, while d3.line() with curveBasis smooths each city's temperature trend. The chart uses d3.axisLeft and d3.axisBottom with gridlines, and a custom colorLegend function renders categorical colors via d3.scaleOrdinal. SVG rendering with mix-blend-mode multiply overlays the lines, and the visualization concludes with a title reflecting the global scope.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5413a4e4792941fab9074325c922af6a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
