A recently released Google Labs product called Fusion Tables allowed users to grab data from spreadsheets, text documents, PDFs and other sources and create compelling, comprehensive visualizations from a merged data set.
Google has just announced it's releasing an API for Fusion Tables. The API integrates with Google Maps, App Engine, Base Data and Visualizations APIs, as well, to allow for motion charts, timelines, graphs and maps with all the data available and running on Google's infrastructure. The API allows users to upload data from any source, from text files to full databases, and see their data merged and compared in cool visualizations. Surprisingly, that's not even the best part.
