This visualization combines an area chart with D3’s `scaleTime` and `scaleLinear` to show world population growth from 1960 to 2015, using a smoothed `curveBasis` path. It loads CSV data via `d3.csv` and formats y-axis ticks with `format('.1s')`. The SVG render includes labeled axes with gridlines from `axisBottom` and `axisLeft`, while the maroon-filled area emphasizes population magnitude over time.
