I can't change the zoom on my Google Map

Hello there,

I am trying to zoom out a bit on my google map generated by ACF. I changed zoom’s value in the object “args” from the default 16 to all sorts of numbers but that changes nothing.

function render_map( $el ) {
		// var
		var $markers = $el.find('.marker');

		// vars
		var args = {
			zoom		: 9,
			center		: new google.maps.LatLng(0, 0),
			mapTypeId	: google.maps.MapTypeId.ROADMAP
	};

How can I change the zoom on my map?
