Sorry to be stupid – I read that, and I understand how to call latitude and longitude!!!! What I don't understand is how to "make" a Google map from this…. I think I misunderstood what the Google Maps API was. The part in your example I particularly don't understand is:
<div class="clearfix">
<div>
<a class="js-map-fitbounds" href="#">Center map to view all points</a>
</div>
[wpv-layout-meta-html]
<div id="js-main-map-canvas" class="google-maps team-map-height"></div>
</div>
Could you give me a step by step?
