javascript - with - http chart apis google com chart

Google charts dynamic icons deprecated. Alternatives? (2)

Im using this to create markers, e.g:|FF9900

or even

return new google.maps.MarkerImage("|" + hexColor,
            new google.maps.Size(21, 34),
            new google.maps.Point(0,0),
            new google.maps.Point(10, 34));

But the title says

Image Charts (Deprecated)

Does anyone know for how long it will be usable? Are there any alternatives?
