Area charts are created using the AreaMark. AreaMark is ideal for visualizing continuous data trends over time or categories by filling the space beneath a line to emphasize volume or magnitude.

This type of chart is especially useful for showing how values accumulate or fluctuate, making patterns easier to see at a glance compared to a line chart alone.

With AreaMark, you can create a variety of area chart styles—including stacked, overlapping, or gradient-filled areas—using just a few lines of SwiftUI code.
