This grouped bar chart displays sales data for six product categories (Electronics, Clothing, Groceries, Furniture, Toys, Books) across six months (January through June). The chart shows monthly comparisons using color-coded bars, with dollar amounts on the y-axis and months on the x-axis. The visualization is generated using D3.js v5 with an SVG rendering approach, employing `d3.scaleBand` for the categorical x-axis, `d3.scaleLinear` for the y-axis, and `d3.scaleOrdinal` for category colors. Data is hardcoded in the script, and axes are labeled with "Month" and currency-formatted tick values.
