This visualization shows the basic cost of Netflix subscriptions across different countries with live data. It renders a bar chart using React to manage the component structure and D3 to calculate scales, axes, and positions. The code imports data from a CSV file and uses `d3.scaleBand` for the x-axis and `d3.scaleLinear` for the y-axis. It employs `d3.axisBottom` and `d3.axisLeft` to create labeled axes, while a tooltip appears on hover. The visualization updates smoothly through React’s state management, combining declarative UI with D3’s data-driven utilities.
