{"version":"1.0","type":"rich","title":"Line Chart with Multiple Lines","description":"This line chart displays one week of temperature data for cities worldwide, sourced from Data Canvas - Sense Your City. Each line represents a city, with temperature on the y-axis and time on the x-axis. The code uses d3’s `scaleTime`, `scaleLinear`, `scaleOrdinal`, `axisBottom`, `axisLeft`, `line`, and `curveBasis` to create smooth, colored paths with `nest().key()` for grouping. A custom `colorLegend` function renders the categorical color scale, while `mix-blend-mode: multiply` gives overlapping lines a blended appearance.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/03a5710d7f3146d8b6edfd509619b07c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
