This is an example of a single layer dot map. Debug is turned on to show outputs and enable clicking on the layer dots.  The ChainID column in the table is displayed onhover. layer.show() is called to show the layer on top of the map.

Note: ml.onload is used to ensure the MapLarge API is properly loaded in the DOM. Wrap the MapLarge API in ml.onload() to ensure availability of all functions and methods. If using jQuery this can be a replacement for document.ready
