Lazy load a script

Not an issue, but a question.

On my site I have a script running to display a map with ship data. Loading this script requires a lot requests. It would be handy/efficient to only load it when it enters the viewport. The script is:
```

var mst_width="96%";var mst_height="350px";var mst_border="0";var mst_map_style="simple";var mst_mmsi="244770624";var mst_show_track="true";var mst_show_info="true";var mst_fleet="";var mst_lat="";var mst_lng="";var mst_zoom="";var mst_show_names="0";var mst_scroll_wheel="true";var mst_show_menu="true";
```

Is there a possibility to use Lozad to lazy load this script?

Thanks in advance!
