  // This example creates two table charts side by side. One uses a data view definition to
  // restrict the number of displayed columns.

  // Get sample data from a spreadsheet.
  var dataSourceUrl = 'https://docs.google.com/spreadsheet/tq?range=A1%3AF' +

  // Create a chart to display all of the data.
  var originalChart = Charts.newTableChart()
      .setDimensions(600, 500)
      .setDataSourceUrl(dataSourceUrl)
      .build();

  // Create another chart to display a subset of the data (only columns 1 and 4).
  var dataViewDefinition = Charts.newDataViewDefinition().setColumns([0, 3]);
  var limitedChart = Charts.newTableChart()
      .setDimensions(200, 500)
      .setDataSourceUrl(dataSourceUrl)
      .setDataViewDefinition(dataViewDefinition)
      .build();
