This example displays world population trends from 2010 to 2022 using an area chart rendered with D3 v5 in SVG. The chart combines a red line and semi-transparent black fill to emphasize population growth over time, with green tick labels and a yellow grid. Data is loaded from a CSV via `d3.csv` and processed with `d3.scaleTime` and `d3.scaleLinear`. The line and area paths are generated using `d3.line` and `d3.area` with `curveBasis` smoothing, while axes are drawn with `d3.axisBottom` and `d3.axisLeft`.
