Create multiple instances of an object.

I m trying to create a point cloud data visualiser in Qt3D using QML. Following code creates a point in 3D display:

SphereMesh {
        id: sphereMesh
        radius: 3
    }

    Transform {
        id: sphereTransform
        property real userAngle: 0.0
        matrix: {
            var m = Qt.matrix4x4();
            m.rotate(userAngle, Qt.vector3d(0, 1, 0));
            m.translate(Qt.vector3d(20, 0, 0));
            return m;
        }
    }

Entity {
        id: sphereEntity
        components: [ sphereMesh, material, sphereTransform ]
    }

I want to use above snippet to create millions of spheres representing points. I see there is a Repeater functionality in QML but how to use it in this case, I used below sample code to run and test Repeater then it gave error for "Column" and "Text" not a type.

Column {
        Repeater {
            model: ["apples", "oranges", "pears"]
            Text { text: "Data: " + modelData }
        }
    }

How to incorporate multiple instances of sphere each with different transform and ids?
