{"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 the Data Canvas - Sense Your City initiative. The visualization plots time on the horizontal axis and temperature in degrees Celsius on the vertical axis, with each city represented by a distinct colored line. Built with D3 version 5, the code uses `scaleTime`, `scaleLinear`, and `scaleOrdinal` for scales, along with `axisBottom` and `axisLeft` for axes. A `nest` operation groups data by city, and a custom `colorLegend` function renders the categorical color key. Multiple lines are drawn using `line()` with a basis curve, rendered as SVG paths.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/fa8afbab6dbb4991aa837caeb025b6c8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
