Line Chart with Multiple Lines
This line chart displays annual carbon dioxide emissions per capita for the top 10 countries, using multi-color lines to compare trends over time. The visualization reads data from a CSV file and renders it as SVG, with each line representing a country, a color legend for identification, and labeled axes for year and emissions. The implementation uses D3 v5 APIs including `d3.csv`, `d3.line`, `d3.scaleTime`, `d3.scaleLinear`, `d3.scaleOrdinal`, and `d3.nest`. A custom `colorLegend` function generates the legend, and gridlines and axis labels are styled for clarity.
