Figure 2.20 in Section 2.2.1 Using Scatter traces refers to 3 layout options but shows only 1

Custom geographic and mapbox layout options are not displayed when viewing the plotly book on Chrome.

Additionally, when pasting the code onto my computer (using RStudio) the custom geographic layout is blank. For mapbox, I was informed that a token was required (I did not look into this further).
On inspecting the blank plot region for custom geographic layout and hitting the console tab, I see an error "Failed to load resource: Unable to init SSL Context:"

I have just reviewed Plotly issues 356 and 1111 and wondering if it is a problem with working behind a firewall? Although would that also affect viewing the book on Chrome?
