An aggregate expression defines a calculation that is processed over a set of data. Schema: [operator: string, initialValue?: boolean | number, mapExpression: Expression] operator: An expression function that is then applied to against all values calculated by the mapExpression for each point in the cluster. Supported operators: o For numbers: +, *, max, min o For Booleans: all, any initialValue: Optional, an initial value in which the first calculated value is aggregated against. mapExpression: An expression that is applied against each point in the data set.
