{"version":"1.0","type":"rich","title":"Line Chart with Multiple Lines","description":"This line chart displays one week of temperature readings in degrees Celsius across multiple world cities, with each city represented by a distinct colored line. The visualization uses D3 v5’s scaleTime, scaleLinear, scaleOrdinal, and nest to group data by city, while a line generator with curveBasis smooths each temperature trend. A color legend, rendered via a custom colorLegend module, identifies the cities. The data comes from the Data Canvas - Sense Your City dataset, loaded as CSV, and the chart is drawn as SVG with gridlines and axis labels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/881120249dda4c2cb93747914a5cf683?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
