This area chart shows the growth of e-commerce sales in billions of USD over time. The chart uses D3.js v7 with an SVG rendering approach, employing `d3.scaleLinear` for both axes and `d3.area` to generate the filled path. The visualization is built from a CSV file loaded via `d3.csv`, with axes labeled "Year" and "E-commerce Sales (Billions USD)". The area is filled with a light blue color, clearly depicting the upward trend of the data.
