Is it possible to mimic the continuous color renderer for a graphics layer as shown in this documentation?
A graphics layer does not use the renderer property so this aproach is not possible.
This graphics layer is dynamically created so the values would be different depending on the query of the layer.
I am able to do this with a feature layer:

I would like to use the following stop values:
stops: [
{
value: 0,
color: "#0c7f3f",
label: "0"
},
{
value: 15,
color: "#69bd45",
label: "15"
},
{
value: 30,
color: "#f3ec0c",
label: "30"
},
{
value: 45,
color: "#f57f22",
label: "45"
},
{
value: 60,
color: "#ee2025",
label: "60"
},
{
value: 300000,
color: "#9e9fa0",
label: "90 <"
}
]
