A bar chart displays monthly sales figures for electronic products. Each bar’s height encodes the numeric Sales value from the CSV dataset, with product names on the horizontal axis and a linear sales scale on the vertical. Repeating product names across rows aggregate into multiple bars per category. Built with React, the visualization uses D3’s `csv` parser to load data, `scaleBand` and `scaleLinear` for axes, and SVG `rect` elements for rendering, with bars filled in steelblue.
