This line chart displays monthly e-scooter sales data from a CSV file, plotting sales values as a steelblue line with orange circular points. The visualization uses D3 v7 to construct SVG elements, with `d3.scalePoint` for the categorical month axis and `d3.scaleLinear` for the sales axis. Axis rendering uses `d3.axisBottom` and `d3.axisLeft`, while the line itself is generated via `d3.line`. The chart includes labeled axes and a title, with data loaded through `d3.csv`.
