Scattermapbox issue with markers/plotting coordinates

[kevalshah90]

Hey Timothy, Thanks for sharing this. Great help as I was building my application in Dash.

I am trying to figure out an issue with the library and was hoping to share the code with you. Basically, I haven't been able to add markers or plot the data on the map. The map itself renders fine.

I opened the issue here: plotly/plotly.py#1223

If you don't mind having a look at the code, I'd appreciate it.
