db access via interactive tags map

I want to create an interactive tags map, kinda like 'visual thesaurus' (http://www.visualthesaurus.com/), and use it as an a access portal to my DB (display tagged data in a separate area), what do you think wo开发者_运维问答uld be the best technology to use?

I need something that would be SEO friendly of course, easy to use (user wise), and easy to program...

Any thoughts?

tnx Liat.
