Is your feature request related to a problem? Please describe.
Right now the map shows the situation on the entire world. If I'm only interested in a certain country. then I'm distracted by not relevant data.

Describe the solution you'd like
I would like to be open the map with an additional parameter named "country".

Example:

https://map.airgradient.com/?zoom=6&long=20.30&lat=56.36&meas=pm25&wind_layer=false&org=ag&embedded=false$country=CH

Do you already have any ideas for the UI design?

If not, how about adding a dropdown menu at the top-right corner of the map, where users can select any country (including those with and without our monitors)?

Once a country is selected, the map would automatically move to focus on that area.

What do you think?

I think this is a good idea. Since there are many countries, we might consider to use a searchable dropdown.
