Uses seaborn.kdeplot to render a smooth density surface over the given

immediately without painting anything.

Args:

ax: matplotlib Axes to draw on.

xs: X coordinates (longitude or projected x).

ys: Y coordinates (latitude or projected y).
|

cmap: Matplotlib colormap name for the density fill. Default "magma".
|
||
alpha: Opacity of the density overlay (0–1). Default 0.35.
|
||
thresh: Density threshold below which contours are not drawn (0–1).
|
||
Default 0.02 removes very sparse outlier contours.
|
||
levels: Number of contour levels. Default 30.
|
||
bw_adjust: Bandwidth adjustment factor for the kernel. Values < 1
|

produce tighter, more detailed estimates. Default 0.6.
