This line chart shows the total book sales across published years for the top 10 book-selling countries. The visualization uses D3 v5 APIs including `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and `line` to render an SVG path. Data is loaded from a CSV file using `d3.csv`, with dates parsed via `d3.timeParse` and numeric sales values. The chart displays clear axis labels and grid lines, with the line path styled in aqua.
