{"version":"1.0","type":"rich","title":"Line Chart with Multiple Lines","description":"This line chart displays a week of temperature readings (in degrees Celsius) from cities worldwide, sourced from Data Canvas - Sense Your City data. The chart plots each city as a separate colored line, using a smooth curve (curveBasis) to connect temperature measurements over time. The visualization is rendered as an SVG using d3.v5, leveraging scales and axes from `scaleTime`, `scaleLinear`, and `axisLeft`/`axisBottom`. The code nests data by city with `nest()`, assigns categorical colors via `scaleOrdinal(schemeCategory10)`, and includes a custom color legend built through the `colorLegend` function.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2c9c53a61cf14961b2d8a994b454c34d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
