{"version":"1.0","type":"rich","title":"Line Chart with Multiple Lines","description":"This example displays CO2 emissions by country, plotting profit against sub-category over time, with each region represented by a distinct colored line. The visualization uses D3 v5 within a Vue framework, rendering to SVG. It employs `d3.line` with `curveBasis`, `d3.nest` to group data by region, and `d3.scaleOrdinal` with `schemeCategory10` for coloring. Axis labels and legends are added via `d3.axisLeft`, `d3.axisBottom`, and a custom `colorLegend` function, based on sample data from annualco2.csv.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8bd8d9b370f54cc4b44e6c6037c5e700?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
