How to create you own Google Maps data mashup?

I have read  a very good article about create Google Maps data mashup.

Here is the link: http://glearningblog.blogspot.com/2011/09/ingredients-google-search-google-fusion.html

After I read the whole article, I find Google Map s is not only one of the best sites for maps and directions. Everyone can mash together your own personal data with a Google map, and place the resulting mashup on your own website. In essence, you’re creating an overlay for your data, from the information in the Google Maps database, and that overlay is displayed on top of the appropriate Google map.

Here is the examplehttps://www.google.com/fusiontables/DataSource?snapid=S249783bb35

Like the example, you can use Google Map to collect all the information about Austrian college. And all the data could be edit, filter and visualize as table, map, bar, pie, intensity map and line, which is very convenient to analyze and interpret. Of course, it can used for daily life like creating a map of your company’s headquarters, so that visitors can see where you are. Or you could get really fancy and map a collection of different locations on a single map—multiple retail stores, for example, or maybe properties for sale or rent in a given area.

Google Map can really expand my outlook and I hope I can apply it in my work in the future.
