{"version":"1.0","type":"rich","title":"Line Chart with Multiple Lines","description":"This line chart displays one week of temperature data across multiple cities worldwide, with each city represented by a distinct colored line plotted over time. The visualization uses d3.scaleTime and d3.scaleLinear to map timestamps and temperature values, while d3.line with curveBasis generates the smoothed paths. A nested data structure organizes measurements by city, and a custom colorLegend component renders the categorical scale using d3.scaleOrdinal with schemeCategory10. The chart includes gridlines, axis labels, and a title, with data loaded from a CSV file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/01cccdd59e4742db8c880d762a630576?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
