Alaska-county map appears too small when generated using Plotly figure factory Choropleth maps

Hi

I am new to Plotly and I wanted to generate Alaska state map with its counties using Plotly Choropleth Figure Factory. I could generate the map with scope as “Alaska” and convert it to image using Kaleido. I generated the map using counties FIPS code.
But the map appears very small way too left with the counties almost invisible or very small.

I could move it to the center setting a left margin. But I am not able to make the map bigger like other states of the US.

Can you please guide me how to get the Alaska map with its counties with a proper zoom level and resolution?
