Help Centering Geo Map

[caboddie1]

Hello. Thank you for this great project, it has been extremely useful so far.

I have built a Choropleth map of England and Wales. I am wanting to show a small section of the map within a modal after clicking an area. This part is working; however, I am unable to center the map within the SVG. Depending on the area, most of the time it falls outside the SVG. As the map shown is different each time, I can't hardcode values like I have done with the main map. I have seen some examples of how to do this within d3 but, I am not sure how that would translate to visx.

Please see an example in the Sandbox below, any help would be appreciated.
