{"version":"1.0","type":"rich","title":"D3 Course 13: Line Chart with Multiple Lines","description":"This line chart displays temperature readings over time across multiple cities, with each city represented by a distinct colored line and a sorted color legend. The visualization uses D3 v5 APIs including `d3.nest()` to group data by city, `d3.line()` with `curveBasis` for smooth paths, and `scaleOrdinal` with `schemeCategory10` for colors. Data loads from a CSV file containing one week of sensor measurements. The chart applies blended stroke modes and rounded line caps for aesthetic distinction.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/84e101413b754039bae98969229cfb99?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
