This area chart visualizes monthly bike sales in the USA from 2022 to 2023, using a steelblue filled region with 60% opacity to show sales trends. The visualization uses D3.js v7 with SVG rendering, loading CSV data from a GitHub gist. It employs `d3.timeParse`, `d3.scaleTime`, `d3.scaleLinear`, and `d3.area` to generate the chart, with axes formatted using `d3.axisBottom` and `d3.axisLeft` for month and sales values respectively.
