This example shows US cancer cases from 2009-2022 as a combined line and area chart, with GDP as the y-axis and year as the x-axis. The chart is rendered using D3 v5 with SVG, using scaleLinear for both axes and d3.line, d3.area, and curveBasis to draw the smoothed line and filled area beneath it. Data is loaded as CSV from a GitHub gist, and the axes use tick marks with removed domain lines. The visualization applies a blue color to the area fill and a bold black stroke for the line, with a prominent title and axis labels.
