This bar chart displays the top 10 countries by total merchandise exports in 2017, measured in millions of US dollars at current prices. The data originates from the World Trade Organization. Using D3 v5, the visualization employs `scaleLinear` for the x-axis, `scaleBand` for the categorical y-axis, and `axisLeft` and `axisBottom` to render the axes. Each country is represented by a green SVG rectangle, with the chart rendered in SVG within an HTML page.
