This line chart displays bike users from 2012 to 2022, with time on the x-axis and user counts on the y-axis. The SVG visualization uses d3.scaleTime and d3.scaleLinear for scaling, d3.axisBottom and d3.axisLeft for axes, and d3.line to generate the path. Data is loaded via d3.csv from a GitHub gist, then parsed with Date and numeric conversions before rendering.
