{"version":"1.0","type":"rich","title":"Line Chart with Multiple Lines","description":"This interactive line chart displays one week of temperature readings in Celsius for multiple global cities, sourced from Data Canvas - Sense Your City. The visualization uses `d3.line` with `curveBasis` to create smooth paths, `d3.scaleTime` and `d3.scaleLinear` for axes, and `d3.scaleOrdinal` with `schemeCategory10` for color assignment. A custom `colorLegend` module renders the city key, while data parsing and nesting rely on `d3.csv` and `d3.nest` to group readings by city. The SVG output includes grid lines, axis labels, and a title.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c422c536a96e46beb2c6f36660e35969?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
