I a simple well arranged and clean Dashboard Website. It connects to my Zabbix 7.4.9 instance via API.
I have around 40 KFC Restaurants that I Need to monitor. First distinction is by Country: Austria and Slovakia .
The Dashboard Needs two views: per Restaurant and per device type.
Per Restaurant: All hosts with a specific "customer" tag (tag value is "QWE"). Item identifier is tag "location".
Per device type: this is based on the host group. 
Graphical representation of one item (restaurant/location and device type) is with a hexagon, circle, etc. Feel free to make a suggestion.
