This visualization displays the basic cost of products sold across fifteen countries, using horizontal bars whose lengths encode the financial value for each country. Built with React and D3 v5, the code renders an SVG chart by mapping country names to a d3.scaleBand y-axis and cost values to a d3.scaleLinear x-axis. The data is loaded from a CSV file via d3.csv, and the bars are drawn as SVG rectangles within a transformed group.
