The library seems to not be working properly.
I get the following I tried to it with jQuery 3.6.0:

Below is a part of my HTML file
....
$(document).ready(function(e) {
$('img[usemap]').rwdImageMaps();
});
</script>
<script src="js/jquery.rwdImageMaps.js"></script>
<script src="js/jquery.rwdImageMaps.min.js"></script>
