{"version":"1.0","type":"rich","title":"Fork of Line Chart with Multiple Lines","description":"This fork of a D3 v5 line chart visualizes one week of temperature data for cities worldwide, sourced from Data Canvas – Sense Your City. The SVG rendering uses `d3.scaleTime`, `d3.scaleLinear`, and `d3.scaleOrdinal` with `d3.schemeCategory10` for color encoding. Lines are generated via `d3.line` with `d3.curveBasis`, while a custom `colorLegend` function handles the categorical legend. Data is loaded from a CSV, parsed with timestamps converted to `Date` objects, and nested by city using `d3.nest`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/74eb0069b436487998c9c853d5fcd573?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
