{"version":"1.0","type":"rich","title":"Multing Data for Multiple Lines","description":"This visualization displays population trends over time for various regions, with each line representing a different area and color-coded via a categorical scale. It uses d3.line with curveBasis to generate smooth paths, d3.nest to group data by region, and d3.scaleOrdinal for colors. Population estimates from UN data are melted into a tidy format, with axes formatted using d3.axisBottom and d3.axisLeft. A custom colorLegend component renders the legend alongside the SVG chart.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/457afc06945f4b678d86eaca6d8ea49b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
