This visualization shows monthly revenue trends across a year using a green line and red circular data points. The chart is built with D3 v7 and rendered as an SVG, using `d3.scalePoint` for the month axis and `d3.scaleLinear` with `.nice()` for the revenue axis. A monotone X curve smooths the line via `d3.curveMonotoneX`, while `d3.axisBottom` and `d3.axisLeft` generate the labeled axes, with data loaded from a CSV file.
