Hi there! I am very new to Plotly even Python. I try to add single point to a plotly scattermapbox, it works. But when I try multiple points, it doesn’t work. I know it might be a silly question but really confused me… lol… Could you help me to figure out where the problem is? I really appreciate it !

@joychen613 I inspected your code [https://plot.ly/~joychen613/2/nuclear-waste-sites-on-campus/#code](https://plot.ly/~joychen613/2/nuclear-waste-sites-on-campus/#code), and I noticed that your `lon` an `lat` lists in the trace definition are reversed. There is no lat of -122 [https://www.mapbox.com/help/define-lat-lon/](https://www.mapbox.com/help/define-lat-lon/). ---
