This line chart displays monthly revenue trends over time, with each data point marked by a circle and connected by a steelblue line. The visualization uses D3 v7’s `d3.scalePoint` for the categorical month axis, `d3.scaleLinear` for the revenue scale, and `d3.line` to generate the path. Data is loaded asynchronously from a CSV file via `d3.csv`, and rendered as SVG with axis labels and gridlines.
