This bar chart displays the Top 10 countries by total merchandise export in US dollars (millions) for 2017, sourced from the World Trade Organization. It renders each country as a horizontal green rectangle, with the length proportional to its export value. The code uses D3 v5’s `scaleLinear`, `scaleBand`, `axisLeft`, and `axisBottom` to position and label the bars within an SVG. Data is loaded from a CSV file and parsed into numeric values before rendering.
