This is a few months old, but interesting enough to post. MIT’s SIMILE project has a great JavaScript visualization framework available called Exhibit.
Exhibit is a three-tier web application framework written in Javascript, which you can include like you would include Google Maps. If you just want to show a few hundred records of data on maps, timelines, scatter plots, interactive tables, etc., why bother learning SQL, ASP, PHP, CGI, or whatever when you can just use Exhibit? To use Exhibit, you write: a simple data file, and an HTML file in which you specify how the data should be shown. Data + Presentation. That’s all there is to publishing, as it should be.
Examples include a faceted browser for Senators.
On the todo list, there are hints of connecting to Freebase:
Connect to freebase using the freebase api [http://www.freebase.com/view/documentation/ here]. First show how standard exhibits can be built with freebase backend; then explore editing the exhibit in order to edit the freebase data.
