This line chart displays the number of Android users over time, with years on the x-axis and user counts on the y-axis, both labeled accordingly. The visualization uses D3 v5 with an SVG rendering, employing `scaleTime` for the temporal axis, `scaleLinear` for the numeric axis, and `line` to generate the path. Data is loaded from a CSV file via `d3.csv`, with dates parsed using `d3.timeParse`. The chart includes gridlines, axis labels, and a red line path styled through an external CSS file.
