Widget support in dashboards

Is there a way to import a widget (not a picture) in a dashboard tile?

For example https://widget.airnow.gov/aq-flag-widget/?a=today&z=98008&n=BELLEVUE is a widget that renders:
image

You could try an iframe tile, something like this driver...

metadata{
	definition( name: "HTML Device", namespace: "tchoward", author: "Thomas Howard") {
        capability "Actuator"
        
		// Indicate what capabilities the device should be capable of
		attribute "html", "string"
        
        command "setHTML", ["String"]
    }
    
    
	preferences{
	}
}

def setHTML(str) {
    def event = createEvent(name: "html", value: """<iframe style="width: 100%; height: 100%;" src="${str}"></iframe>""");
    sendEvent(event);
}
