This line chart visualizes world population from 1950 to 2020. The chart uses D3 v5 with an SVG renderer, employing `d3.scaleTime` for the year axis and `d3.scaleLinear` for population values. A `d3.line` generator creates the red population trend path, with axes labeled via `d3.axisBottom` and `d3.axisLeft`. Data is loaded as CSV from a GitHub gist, with year values parsed as dates.
