D3, Google Maps, selection of d3 elements

advertisements

Per this example, I am trying to add marker selection, (i.e. add .on("click"...) to the marker variable). However, when you bring the mouse over the google maps canvas, you get the hand that lets you drag, and you cannot select any svg elements with it.

Is there a way to (temporary) disable that feature so you can click the D3 elements?

I'm working on building a map like this right now. I haven't used Google's markers (rather d3 SVG circles) but I found mouseover/click/etc events had to be on objects in the overlayMouseTarget layer of the map:

var overlay = new google.maps.OverlayView();

overlay.onAdd = function() {

    var layer = d3.select(this.getPanes().overlayMouseTarget)
        .append("div")
        .attr("class", "providers");
             ...
}

I think the gMaps demo on d3js.org uses a different layer.
