This visualization displays the world population by year from 2015 data, presenting the trend as a smooth area chart. The chart uses a time-scaled x-axis and a linear y-axis to show population growth over time, with a pink filled area and steel blue stroke. The visualization is rendered using D3 v5, employing `scaleTime` and `scaleLinear` for axes, `area` and `curveBasis` for the area path, and `axisLeft`/`axisBottom` for the axes. The data is loaded from a CSV file and processed before rendering.
