This fork of Task 3 displays monthly expense categories as overlapping filled areas in an SVG area chart, using d3.area to stack housing, food, transportation, utilities, and entertainment values. The code loads data from monthly.csv, applies d3.scalePoint and d3.scaleLinear for axes, and colors each category with d3.scaleOrdinal and d3.schemeCategory10. Semi-transparent fills allow categories to be compared across months, with axis labels generated via d3.axisBottom and d3.axisLeft.
