Explore extensibility of Voyager 2

It looks like it [wouldn't be _too_ hard](https://github.com/vega/voyager#embed-voyager-datavoyager-library) to get a voyager2 page running, that pulls data from the server running the API (put thought into what data types are wanted, and how they should be merged) and then takes advantage of the interactive, recommender-enable visualizations offered by Voyager 2. Check out [this video](https://vimeo.com/199084718) for a cool overview of the features of Voyager 2.

Some unique considerations may have to be applied, since a feature table is not exactly neatly tabular (or all that informative on its own), i.e., both samples and observations have their own metadata that are important for making conclusions about the data.

Start with the Voyager 2 embed documentation and the API server described in the issue. Determine which feature-table data, samples, observations, and metadata the page should consume and how they should be merged; done means a working Voyager 2 page that retrieves the data and supports its interactive visualizations.
