This line chart visualizes the world population from 1960 to 2015, using a filled area curve to show the trend over time. The visualization is rendered in SVG using D3.js, employing `scaleTime` for the x-axis (years), `scaleLinear` for the y-axis (population), and the `area` generator with `curveBasis` to create the smooth, filled shape. Data is loaded as CSV from a remote URL, and axis labels and titles are styled with CSS.
