This area chart visualizes world population trends from 2010 to 2020 using a line to trace yearly values and a filled yellow region beneath it to emphasize magnitude. Built with D3 v5, the visualization loads a CSV dataset and applies time and linear scales to map years and population counts. The SVG output features styled axes with tick marks, axis labels, and a smoothed curve generated through d3.line and d3.area with curveBasis. The chart demonstrates population growth over the decade while showcasing D3's data binding and SVG rendering capabilities.
