One more question Many thanks for your previous kind response, @giswqs
Can we add custom markers in png or jpeg to our point-shape file or geojson or csv data?
i have tried a lot but all in vien
can we add png as marker in this code?
i have learned on website too but am unable to understand it

import leafmap
m = leafmap.Map(center=[23, 69], zoom=4)
shp_path = 'data/point.shp'
point_style = {
'radius': 0.1,
'opacity': 1.0
}
m.add_shp(
shp_path,
layer_name='Point Layer',
style=point_style,
