World Population Area Chart
This area chart visualizes world population over time using data from the United Nations’ 2017 World Population Prospects (VizHub dataset), with a maroon filled path under a curve. The SVG render uses D3 v5 APIs including `scaleTime`, `scaleLinear`, `area`, `curveBasis`, `axisBottom`, and `axisLeft` to build axes with grid lines and custom tick formatting (e.g., abbreviating billions). It also demonstrates axis-label placement, margin-based layout, and title styling via CSS classes.
