This line chart shows the number of U.S. immigrants per year from 2006 to 2021, with the year on the x-axis and immigrant counts on the y-axis. The data is loaded from a CSV file hosted on GitHub using d3.csv. The visualization uses d3.scaleTime, d3.scaleLinear, d3.axisBottom, d3.axisLeft, and d3.line to render an SVG path, with styled tick lines, axis labels, and a title. The chart displays red line segments on a white background with labeled axes.
