This area chart visualizes world population growth over time, with the x-axis mapping years and the y-axis mapping population counts. The chart uses a maroon filled area to represent the data, overlaid with grid lines and labeled axes for clarity. Built with D3 v5, the code loads data from a CSV file, parses the year as a date and population as a number, then renders the chart using scalable vector graphics. It employs D3's area generator with a basis curve for smoothing, along with time and linear scales, and axis components to create the final visualization.
