This line chart shows COVID-19 total deaths by country across the first ten rows of a CSV dataset, sorted by country name. The visualization uses d3.v7 to create an SVG chart with a blue line plot, a banded x-axis for countries, and a linear y-axis for death counts. It fetches data asynchronously via `d3.csv`, filters to ten entries, and draws axes and the line path within a defined margin. Axis labels are added as SVG text elements, and the chart title dynamically reflects the y-axis label.
