A horizontal bar chart ranks the 80 most obese countries by obesity rate in 2014, using country names on the x-axis and numeric values on the y-axis. The data, loaded via `d3.csv`, is sorted in descending order with `d3.descending` before slicing to ensure an accurate top list. The visualization is built with the vega-lite-api library, configured with `vl.markBar()`, and rendered as an SVG through `vega` and `vega-lite` with a custom dark theme.
