This line chart visualizes the annual active player counts on the Steam platform from 2013 to 2023. The SVG chart uses d3.scaleTime and d3.scaleLinear to map years and player counts, with d3.axisBottom and d3.axisLeft rendering grid-lined axes. A d3.line generator draws the path, while d3.csv loads data from a GitHub gist, parsing values with d3.timeParse. The chart features a gradient background and custom styling through CSS classes for the line, tick labels, and axis labels.
