This example displays world population over time as a line chart, with time on the x-axis and population on the y-axis. It uses D3 v5’s `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and `line` generator to render the SVG path and axes. Data is loaded from a CSV file using `csv()` and parsed for the visualization. The chart includes labeled axes, a title, and gridlines with tick marks.
