Map for switzerland (swz?) not working

[fabpico]

I want to show a map of Switzerland. I assume the used abbrevation in the library is swz.

With the datamaps.swz.min.js approach, I get a blank page. But works with usa.

<!-- with scope usa: shows usa -->
<!--<script src="lib/datamaps.usa.min.js"></script>-->

<!-- with scope swz: shows nothing -->
<script src="lib/datamaps.swz.min.js"></script>

<div id="container" style="position: relative; width: 500px; height: 300px;"></div>
<script>
    var map = new Datamap({
        element: document.getElementById('container'),
        // scope: 'usa' // works with "datamaps.usa.min.js"
        scope: 'swz' // blank page with "datamaps.swz.min.js"
    });
</script>

With the datamaps.all.min.js approach, I get an error Uncaught TypeError: Cannot read properties of undefined (reading 'swz'). But works with usa.
