I am using the OSM tile provider in bokeh to plot a basemap, here is a reference. I am wondering if there is a way to show the scale of the map in meters or kilometers depending on the zoom level.
Just to clarify, the axis labels can remain in WGS84-pseudo-mercator but I want to have a scale or some sort of ruler to give a better sense of the distances in the plot.
Here is an example image from the OSM website where I have marked the scale in the bottom left corner.
