How we made this example

1. We've created a node "Electricity production" with 4 fields: country, year, source and amount. How to create a node.
2. Added a preview of pie chart type to the node.
3. Added two search filters to the preview - country and year (filters explained).
4. We had a file with data in CSV format (CSV format represents data as a table - you can open it in Excel, for example). Every row in the file contained information about one source of one country in the particular year.
5. Created an import (imports explained).
6. Automatically generated programming code.
7. Imported data from the file.
8. Made some minor modifications to the design.
