dataset_columns
Dataset columns and shape
The columns, which of them are numeric, the row count and the provenance banner of the RollCallWorks dataset. Call this first to learn the schema.
Eingabeschema 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'properties': {}}
dataset_compare
Compare rows side by side
The rows of the RollCallWorks dataset whose column is any of the given values, in the order given — for "X vs Y" questions.
Eingabeschema 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['column', 'values'], 'properties': {'column': {'type': 'string', 'minLength': 1}, 'values': {'type': 'array', 'items': {'type': 'string', 'minLength': 1}, 'maxItems': 10, 'minItems': 2}}, 'additionalProperties': False}
dataset_provenance
Where this data comes from, and how to cite it
The source, the date it was computed, the licence and the citation for the RollCallWorks dataset. Read this to attribute a figure correctly.
Eingabeschema 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'properties': {}}
dataset_row
Look a row up by an exact key
The rows of the RollCallWorks dataset where a column equals a value exactly (case-insensitive).
Eingabeschema 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['column', 'value'], 'properties': {'value': {'type': 'string', 'minLength': 1}, 'column': {'type': 'string', 'minLength': 1}}, 'additionalProperties': False}
dataset_search
Search the dataset
Rows of the RollCallWorks dataset whose cells contain the query (case-insensitive), up to 50.
Eingabeschema 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['query'], 'properties': {'limit': {'type': 'integer', 'maximum': 50, 'minimum': 1}, 'query': {'type': 'string', 'minLength': 1, 'description': 'text to look for in any cell'}}, 'additionalProperties': False}
dataset_stats
Summary statistics for a numeric column
count, min, max, mean, median and sum of a numeric column of the RollCallWorks dataset (grouping commas and currency are handled; non-numeric rows are excluded and counted).
Eingabeschema 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['column'], 'properties': {'column': {'type': 'string', 'minLength': 1}}, 'additionalProperties': False}
dataset_top
Rank rows by a numeric column
The highest (or lowest) rows of the RollCallWorks dataset by a numeric column — "which is the most/least X".
Eingabeschema 
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['column'], 'properties': {'limit': {'type': 'integer', 'maximum': 50, 'minimum': 1}, 'column': {'type': 'string', 'minLength': 1}, 'ascending': {'type': 'boolean', 'description': 'true for the lowest first; default highest first'}}, 'additionalProperties': False}
