How to use the d3-hierarchy.treemapSliceDice function in d3-hierarchy

// Use treemap layout generator ==========================================

let treemapRootNode: d3Hierarchy.HierarchyRectangularNode;

treemapRootNode = treemapLayout(stratifiedRootNode);


// Tiling functions ======================================================

tilingFn = d3Hierarchy.treemapBinary;

tilingFn = d3Hierarchy.treemapDice;

tilingFn = d3Hierarchy.treemapSlice;

tilingFn = d3Hierarchy.treemapSliceDice;

// Tiling Factory functions treemapSquarify() and treemapResquarify() ====

let tilingFactoryFn: d3Hierarchy.RatioSquarifyTilingFactory;

tilingFactoryFn = d3Hierarchy.treemapSquarify;
tilingFactoryFn = d3Hierarchy.treemapSquarify.ratio(2);

treemapLayout.tile(d3Hierarchy.treemapSquarify.ratio(2));

tilingFactoryFn = d3Hierarchy.treemapResquarify;
tilingFactoryFn = d3Hierarchy.treemapResquarify.ratio(2);

treemapLayout.tile(d3Hierarchy.treemapResquarify.ratio(2));
