This line chart visualizes monthly household spending using React and D3 v7, with data loaded from a CSV via `d3.csv`. The chart uses `scaleTime` and `scaleLinear` for the axes, and `d3.line` with `curveBasis` to render a smooth spending trend. Axis ticks are custom-drawn as SVG elements, with gold lines and blue text, while the line itself appears in red. The graph includes labeled axes for months and expenses, and was built as an ICE-7 assignment fork.
