[Feature] Choosing z of points when using a visualMap

[VictorTolosanaCOVARIANS]

What problem does this feature solve?

When using visualMap (piecewise), there's no way to choose the z of points. With a large dataset on a scatter they may overlap and make the graph unusable, as we cannot choose which ones are drawn on top of the others. Or maybe there's a workaround already available ?

What does the proposed API look like?

visualMap: {
    inRange: {
       z: [2, 1, 3]
    }
}
