This bar chart displays sales data for various items, with horizontal bars showing the sale amount for each item. The visualization uses React and D3 v5, loading CSV data via `d3.csv` and rendering SVG elements with `scaleBand` for the categorical y-axis and `scaleLinear` for the numeric x-axis. Gridlines and axis labels are generated manually using `xScale.ticks()`, while the data values are encoded as rectangle widths.
