{"version":"1.0","type":"rich","title":"Line Chart with Multiple Lines","description":"This line chart compares profit by sub-category for different customer segments and regions. It shows multiple colored lines, each representing a region, plotted across sub-categories with profit values on the y-axis. The visualization uses D3 v5 APIs including `scaleLinear`, `scaleOrdinal`, `nest`, `line`, and `curveBasis` to aggregate and smooth the data. A color legend, built with `colorLegend`, identifies each region. The data, sourced from Data Canvas - Sense Your City, is loaded from a CSV and rendered as an SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/267c5253144243caa3b7cf98659f4559?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
