A horizontal bar chart displays Nobel Prize counts for six countries, with the United States leading at 200. The visualization uses D3 v4 to create an SVG, employing `d3.scaleBand` for the x-axis and `d3.scaleLinear` for the y-axis. Bars are rendered as SVG rectangles with a blue fill, and the chart dynamically updates via a custom `update` function that binds data and adjusts bar heights, widths, and positions based on the scales. The data is hardcoded in the script.
