This bar chart displays the top 10 countries by total merchandise exports in 2017, using data from the World Trade Organization. The chart visualizes export values in billions of dollars, with countries ordered by their export magnitude. Built with D3 v5, the visualization uses `scaleLinear` for the x-axis, `scaleBand` for the y-axis, and `axisLeft`/`axisBottom` for tick marks. The data is loaded from a CSV file via `csv()`, rendered as SVG rectangles, and styled with a steelblue fill.
