A bar chart displays the basic monthly cost of Netflix in fifteen countries, sourced from a CSV dataset. The visualization uses React for component structure and D3 v5 for scales, axes, and SVG rendering. `d3.csv` loads the data, `scaleBand` positions country categories on the y-axis, and `scaleLinear` maps costs to bar widths on the x-axis. Grid lines, tick labels, and rectangles are drawn directly with SVG elements.
