I have a basic Google Store Locator site up on my site.
I need someone to be able to
(i) create a dataset source (static csv, google app engine, mysql, but I prefer fusion table the MOST)
(ii) set up 4 category filters (instead of 'wheelchair access' and 'audio' on the google site)
the .js, .css, .html files are all found in http://code.google.com/p/storeloca
The dataset is found as attached in this posting.
so you have something to start playing with.
