              data={[
                ['Year',  'Expenses', {'type': 'string', 'role': 'style'}],
                ['2013',  400, null],

                vAxis: { minValue: 0 },
                // For the legend to fit, we make the chart area smaller
                chartArea: { width: '50%', height: '70%' },
                // lineWidth: 25
                pointSize: 20,
                // series: {
                //   0: { pointShape: { type: 'star', sides: 5, dent: 0.5 } }
                // }
              }}
              // For tests
              rootProps={{ 'data-testid': '1' }}
            />
