Leaflet

This JavaScript library can be used to create mobile-friendly interactive maps. It does not provide data to map, but can be used to map spatial data in GeoJSON format, or display tiles from other sources such as MapBox.

sheetsee.js

"Sheetsee.js is a JavaScript library, or box of goodies, if you will, that makes it easy to use a Google Spreadsheet as the database feeding the tables, charts and maps on a website. Once set up, any changes to the spreadsheet will be auto-saved by Google and be live on your site when a visitor refreshes the page.
Using Google Spreadsheets as the backend database is awesome because it is easy to use, share and collaborate with." -- website
