@rasika Your image represents a
marker_symbol = 'circle-open' that is an attribute of a
go.Scatter trace. The marker symbols for
go.Scattermapbox are available here https://labs.mapbox.com/maki-icons/. To use one of these symbols, hover the mouse over its image
and copy only it’s name, not the int value at its end, because it represent the image pixel width.
I couldn’t find a circle like your one, but you can check it again, to be sure.
Below is an example with symbol listed as `college-15.svg’.
import plotly.graph_objects as go
fig = go.Figure(go.Scattermapbox(
marker=dict(symbol ="college", size=20)
