Thanks Christina -- 

An image-map like this is an option, but a bit of a painstaking one. For something that needs to operate on a country-by-country basis (as opposed to continent-sized groups as on Pangaea), but shape-creation could get a bit cumbersome. I'm hoping there's a service that might do a good job of handling the heavy-lifting to turn a text list with associated countries into a slick-and-easy filterable list.

After banging on Tableau for a while, and with some help from their support community, I've been able to devise something like what I want (albiet with Tableau's built-in limitations in terms of presentation): 
https://public.tableau.com/profile/ken.irwin#!/vizhome/GraphicTravelogue/Dashboard1 
As a proof-of-concept, I took a bibliography of graphic travel narratives from various countries and put them into this viz. It's not perfect, but it's a start.

Any other ideas out there would be very welcome as well.

Thanks
Ken

https://www.pangaea.de/ has that and I think all their code is open?  I think you can either click on a country or draw a bounding box. 
On the first page you don't get very granular, but on the results from that you can get extremely detailed.

Subject: [CODE4LIB] datavis question: filtering data table by map clicks

Hi folks,

I'm looking for the right tool for the job. I'm helping a faculty member who wants an interactive bibliography: click on the map and get all of the bib entries that pertain to that country. It would be like the visual equivalent of this common way of filtering text with jQuery:

I'm imagining some thing that looks a bit like this, with the country highlighted and the bib details below:

This screenshot cobbles together a couple of views I was able to put together in Tableau, and I imagine that Tableau might be able to support the kind of application we're going for. But maybe a different datavis tool would do it easier, better, etc.

Does anyone know of a tool that would do this sort of filter-by-map-click function? Anyone know what that kind of function might be called? It seems like it would be super-cool, but my Google-fu has failed me thus far.

So far, I can get Tableau to show me the bib details for a single entry when there's only one entry per country, or it will show  me (as seen above) the number of entries for a country with more numerous entries, then it takes a few clicks to get to the bib details.

Any ideas?

Thanks
Ken
