This visualization displays world population as a line chart, plotting year on the x-axis against percentage on the y-axis with pink stroke highlighting the trend. Built using D3 v5, it loads CSV data from a GitHub gist and employs `d3.scaleTime`, `d3.scaleLinear`, `d3.axisBottom`, `d3.axisLeft`, and `d3.line` to generate an SVG path. Gridlines, axis labels, and a title are appended within a margin-based layout.
