When Google first launched their visualization API, you could only use data that was in Google spreadsheets, which was pretty limiting. Yesterday, Google opened this up, and you can now hook in data from wherever you want. What does that mean? It means that developers now have access to all the visualization API offerings like before, but it's now a lot easier to hook visualization into data applications.
Headed for Googley Waters
It also means we're about to see a boom in web applications that look very Googley. Motion charts (above) are going to spread like wildfire and ugly gauges will grace us with their presence. It'll be similar to the Google Maps craze, but not quite as rampant. In a couple months from now, I will have a long list of online places that use the Google visualization API. It's going to be interesting where online visualization goes from here.
Going back to my original question, to what extent do you think the now-open Google Visualization API will affect visualization on the Web?
