This area chart visualizes world population trends from 1950 to 2015, showing population values rising over time with a smooth, curved line filled in teal. The chart uses D3 v5’s `scaleTime` and `scaleLinear` for axes, `area` with `curveBasis` to generate the filled path, and `axisBottom`/`axisLeft` for labeled ticks. Data is loaded from a CSV file, with years parsed as dates and populations as numbers. The SVG rendering includes custom tick styling and axis labels.
