It would be great to have some support for charting hierarchical data in the Angular 2 Components.  It would be especially nice to see something like the old TreeMap widget brought into the library and extended such that the data visualization could change (specifically a sunburst chart option would be really nice).  Additionally, it would be great if there were native functionality in the component to drill deeper into the hierarchy rather than always having to look at the top level view (i.e. clicking a sub node would "zoom in" to view it as the new root level node).

This example treemap and sunburst (implemented using d3.js) are along the lines of what I'm suggesting.
