Parameters

Param	Type	Details
platform	string	Name of the platform (Required if not using `data` attribute).
query	string	Name of the query (Required if not using `data` attribute).
source-field	string	Name of a primary field to facet on (for example “Country”). The values of this facet will define the set of graph nodes with outgoing edges. (Required if not using `data` attribute).
target-field	string	Name of a secondary field to facet on (for example “City”), for every facet value of the primary field. The values of this facet will define the set of graph nodes with incoming edges. For example, say the primary facet (source-field) has values for Country=Germany and Country=France and the secondary facet (target-field) has values for City=Berlin, City=Munich and City=Paris. Then we add graph edges Germany-→Berlin, Germany-→Munich and France-→Paris. (Required if not using `data` attribute).
measure (optional)	string	Name of a numerical measure that defines the weight of each graph edge. When omitted, this defaults to the counts of the facets defined by the target-field. Some possible measures include “sum”, “mean” and “min”. (Only applicable if not using `data` attribute).
measure-field (optional)	string	Field to measure, when the “measure” option is specified.
data	object	Array of arrays containing the data to render the sankey chart. In the format of `['from', 'to', 'weight']` `[ ['Spain', 'Portugal', 100] ['Spain', 'Brazil', 300] ]` (Required if not using the `platform` attribute)
