This example visualizes world population trends from 2010 to 2020 with a single line chart, mapping years on a time-scaled x-axis and population values on a linear y-axis. The SVG rendering uses d3.scaleTime and d3.scaleLinear to position data points, while d3.axisBottom and d3.axisLeft generate gridlines and tick labels. A d3.line generator creates the violet path connecting the parsed CSV data, which loads from a GitHub Gist. Custom CSS styles the axes, ticks, and labels with distinct colors for readability.
