Is it possible to display metric scale bar on a geographic hvplot (gpd.hvplot(geo=True))? For example, if we are viewing a country, is there a way to add a scale bar that indicates how big across the country is in km?

I see that there is this geopandas' issue, but that is using matplotlib-scalebar and I'm using hvplot/bokeh.
I also found this, but that is using bokeh directly, which doesn't know anything about geographic coordinates.

(I asked this question over in geopandas, but they forwarded me here)
