Step #4: Now you need to clean up the data just a little. First, delete the "See categories" in cell A18. Then, because you're going to evaluate individual categories, you need to get rid of the second row -- "All" -- which is the aggregate data for all the categories. Finally, you need to freeze row 1, which has the column labels in it. (If you need help with any of these steps, try googling "how to delete a row in Google Sheets" or "how to freeze a row in Google Sheets" and so on.
Step #5: Name the sheet "[your first name] - Kickstarter data"
Step #7: Import the data from the spreadsheet by clicking going through the next two screens. (Note: Your column headers should be in row 1 in bold.) Once you click finish, your new Fusion Table will be populated with the data from your Google sheet.
Step #10: Configure the pie chart. The Category should be "Category," the Value should be "Launched Projects," and the "Sort by" option should be "Launched Projects." Maximum slices should be 16.
