{"version":"1.0","type":"rich","title":"Line Chart with Multiple Lines","description":"This line chart displays a week of temperature readings in degrees Celsius across multiple global cities, with each city represented by a colored line. The visualization uses d3.scaleTime and d3.scaleLinear to map time and temperature axes, while d3.nest groups the data by city for individual line paths generated with d3.line and curveBasis. A custom colorLegend component renders the categorical color scale using d3.scaleOrdinal. The data comes from Data Canvas - Sense Your City, and the SVG rendering includes gridlines, axis labels, and a title.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/25ba743107ab4f54a64a2c185586c219?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
