{"version":"1.0","type":"rich","title":"Line Chart with Multiple Lines","description":"This visualization displays one week of temperature readings for cities worldwide, with each city represented by a smooth, semi-transparent line. The chart uses d3.line with curveBasis to generate paths, d3.scaleTime and d3.scaleLinear for axes, and d3.scaleOrdinal with schemeCategory10 for colors. A custom color legend uses exported functions from colorLegend.js. Data comes from the Data Canvas - Sense Your City dataset, loaded via d3.csv, with nested grouping via d3.nest to separate city series.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/52f7fbb4d34e40f3aa79bea74f19e9fa?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
