It would be great if hierarchical chart types were available. Currently there's not a good way to represent hierarchical data outside of a TreeMap, but TreeMaps don't always work well (particularly for small datapoints). An ideal chart type would be the sunburst chart (nested pie/donut charts), as it can have multiple layers, hide a segment (and all children), and potentially zoom into child layers.

There are a variety of sunburst examples currently out there from other Javascript libraries:
