Stage 1: Preparing Google Fusion

3. Type 'fusion tables' in the Search Apps box and hit Enter.

   

   
   
4. Click the '+ CONNECT' button and then 'OK'.

Stage 2: Creating a Google Fusion table

1. Click 'NEW' -> 'More' -> 'Google Fusion Tables'.

   

   
   
2. In the 'Import new table' dialog box, click 'Choose file' and select the CSV file.

   

   
   
3. Click 'Next' to review, 'Next' again to advance, and finally 'Finish'.
