Area chart
The area mark draws the region between a baseline (x1, y1) and a topline (x2, y2) as in an area chart. Often the baseline represents y = 0, and because the area mark interpolates between adjacent data points, typically both the x and y scales are quantitative or temporal.
Plot.areaY(aapl, {x: "Date", y: "Close"}).plot()
const aapl = FileAttachment("data/AAPL.csv").csv({typed: true}).then(display);
