This line chart displays population trends for countries from 2013 to 2022, with time on the x-axis and population count on the y-axis. It uses d3.csv to load the data and d3.scaleTime, d3.scaleLinear, d3.axisBottom, d3.axisLeft, and d3.line to render the SVG path. The chart includes rotated axis labels and grid lines via tick sizes, with the line drawn in red. Data is parsed from a GitHub gist CSV, formatting years from date strings using d3.timeParse.
