This area chart shows world population trends over time, with the years on the x-axis and population counts on the y-axis. The visualization uses D3’s `scaleTime`, `scaleLinear`, and `area` generator with a `curveBasis` smoothing function to create the orange population curve. Axes are rendered using `axisBottom` and `axisLeft`, with grid lines and labeled titles. Data comes from a CSV file loaded via D3’s `csv` method, with population values multiplied by 1000 and years parsed as dates before rendering as SVG.
