This fork of ice-7-task2 visualizes monthly expenses across five categories—housing, food, transportation, utilities, and entertainment—as a multi-line chart. The D3 v7 code loads data from a CSV file and renders an SVG with smooth monotone curves for each category, distinguished by a categorical color scheme. It uses `d3.scalePoint` for the month axis, `d3.scaleLinear` for the expense axis, and `d3.line` with `d3.curveMonotoneX` to generate the lines, while also adding individual data points and a right-side legend.
