This example visualizes the average monthly cost of basic internet service across twelve countries using a horizontal bar chart, with country names on the y-axis and cost in dollars on the x-axis. The React component loads CSV data via `d3.csv` and renders the chart as an SVG, using `scaleBand` for the categorical y-axis and `scaleLinear` for the numeric x-axis. Red gridlines, generated from the x-axis ticks, extend across the plot area, while each bar’s width reflects the data value. The visualization omits axis labels and tooltips, keeping the focus on comparing costs directly from the raw data source.
