This combined chart compares grocery spending across ten equal-sized segments of the dataset. A single bar series shows average produce spending, while overlaid line-and-dot series depict average dairy, snacks, and beverages spending using distinct colors. The visualization uses d3.csv to load data, d3.mean for aggregation, and d3.scaleBand, d3.scaleLinear, d3.line, and d3.axisBottom/Left to construct the SVG rendering. The chart is built with d3.v7 inside a React framework, and the initial view includes axis labels and a legend.
