Following query contains example data for the bubble chart. Add it to a dataset with name "exampleData". Note that this example needs QPR Reporting Expression datasource installed.

data=CreateDataset(Array('Risk', 'Value', 'Cost', 'Category'))
data=AddDatasetRow([data], 4, 1, 6, 'Category 1')
data=AddDatasetRow([data], 8, 5, 4, 'Category 2')
data=AddDatasetRow([data], 1, 9, 4, 'Category 3')
data=AddDatasetRow([data], 3, 2, 8, 'Category 1')
data=AddDatasetRow([data], 3, 8, 9, 'Category 3')
data=AddDatasetRow([data], 7, 4, 5, 'Category 2')
data=AddDatasetRow([data], 6, 7, 6, 'Category 1')
data=AddDatasetRow([data], 9, 1, 7, 'Category 4')
data=AddDatasetRow([data], 2, 3, 4, 'Category 1')
data=AddDatasetRow([data], 8, 6, 7, 'Category 4')
