This bar chart displays the basic monthly cost of Netflix in 15 countries, derived from a CSV file loaded via d3.csv. The visualization uses React hooks (useState, useEffect) to manage data fetching, while d3.scaleBand and d3.scaleLinear construct the categorical and quantitative scales. SVG rectangles represent each country’s cost, with axis ticks generated manually using d3’s scale methods. The code combines React’s component model with D3’s data manipulation and scaling functions, rendering all marks directly in JSX within an SVG element.
