#In the code below I have marker labels on the map itself.
# I put this piece of code:
# float(d) + 5 for d in df["longitude"]],
# lat=[float(d) + 0 for d in df["latitude"]]
# to make these labels close to the markers. But in case of resizing of map these labels looks weird.
# I believe that it is possible to put into condition of labels position not only absolute values
# as it is now, but some sort of dependency between labels coordinates and values in data.
