{"version":"1.0","type":"rich","title":"Line Chart with Multiple Lines_a","description":"This line chart displays one week of temperature data for San Francisco, sourced from Data Canvas’s “Sense Your City” dataset. Multiple city lines are plotted over time, with a color legend distinguishing each location, and the lines use a basis curve for smooth rendering. The visualization is built with D3 v5, using `scaleTime`, `scaleLinear`, `scaleOrdinal`, `nest`, and `line` to generate SVG paths. Axes include tick marks and labels, while a title and legend clarify the chart’s content.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e9b2968bb9ac456db878f4a5a54b14fd?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
