{"version":"1.0","type":"rich","title":"Melting Data for Multiple Lines","description":"This example visualizes population projections for global regions from 1950 to 2100 as multiple smoothed lines, each colored by region via an ordinal color scale and accompanied by a legend. The chart uses d3.scaleTime, d3.scaleLinear, d3.axisLeft, and d3.axisBottom to render axes, while d3.line with d3.curveBasis draws the paths. Data is loaded from CSV files and melted into a tidy format before rendering as SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/605c230e42a945e58febda8c66a95505?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
