Plot a Map 

Visualizations can be created via the PAGE ELEMENTS section of your workbook's editor panel or directly from an existing data element

Visualized data will not display on the page canvas until all required plot fields are defined.

Add columns to open fields using either the field's + menu or dragging and dropping the column.

Map Types

Workbooks support three distinct map types: Region, Point and GeoJSON.

You should choose your map type based on your available data and the results you wish to see. For example, if you want to map a text column [State] with cell values like "Colorado" and "California", you should a Region map type.

Map - Region

Region maps require a single text column on the map's REGION field. Rows in this column should match one of the following region types:

  • Counties(e.g. United States, China, Kenya, Brazil)
  • US States (Name)(e.g. Colorado, California, Massachusetts, Oklahoma)
  • US States (Shortcode)(e.g. CO, CA, MA, OK)
  • US Counties (Name, State) (e.g. "Alemeda, California")
    Note: The words "County" or "Parish" must be omitted from the county name. 

Map - Point (Lat/Long)

Point maps require a number column on both the map's LATITUDE and LONGITUDE fields.

Map - GeoJSON

GeoJSON maps require a variant column on the map's GEOJSON field.
JSON blobs allow for storage of more complex geographical data than simple numeric lat/long columns. To plot a GeoJSON column on a map, the column must have a 'coordinates' key.

Example:  { "geometry": {"coordinates": [-94.042964, 33.019219] } } 

Pro-tip: If your GeoJSON data is stored as a text column (abc), you can convert it to a variant using Sigma's Variant function.
