Google Labs has a new service for visualizing data Google Fusion Tables. The utility focus is on data management, collaboration, merging multiple data sources, querying, visualization, and along with this publishing it on the web in various forms. You can upload your own data tables from spreadsheets or CSV files of size up to 100MB per table, and up to 250MB per user. You can also export your data in CSV format.
Once your data has been imported you can visualize it instantly. See the data on a map or as a chart immediately. Columns with locations are interpreted automatically, and you can adjust them directly on a map if necessary. Filter and aggregate tools are also provided for more selective visualizations.
You can merge your data with other data tables. When another table has information about the same entities, merge the tables together to see all information in one place. When any data table is updated, the merged table will show the latest value too.
Multiple people can view and comment on the data. Discussions display people’s comments and any changes to the data over time. Define a subset table to share. Choose only the columns you want to share with others. Save as a linked table with its own share permissions that will always show your current data values.
There are many options to visualize the data. Just like in Google Docs you can invite collaborators to view, contribute columns or edit. Just enter the email addresses of the people with whom you want to share a table and send them an invitation. You can specify attribution for the data which will appear even when your data is merged into other tables.
The best part is that now as you’ve got that nice map or chart of your data, you can embed it in a web page or blog post. It will always display the latest data values for your table.
