How to show hover info on county Choropleths?

Hi all,

I’m trying to get a better understanding of making maps in plotly, specifically choropleths. I have been working through the examples on this page, and I am able to replicate everything correctly, but I am having trouble understanding how hover info is displayed.

In the first example on the page (Simple Example), hovering over the highlighted counties shows some information about those counties. However, in each of the following examples on the page no hover info is shown. Even on the last one (The Entire USA) where show_hover=True and a centroid marker is created.

Normally I would think this is a problem with my code, but this is happening right on plotly’s own page.

My hypothesis is that you just can’t have hover info when there are more than a few counties, but I would like some experts’ opinions and insights.

Thank you all in advance for the help!
