Choropleth US state map

Cloudera Data Visualization Map visuals let you plot measurements, as areas, over US State regions.

A map of the United States shows a comparison of measurement values among US States. The following steps demonstrate how to create a new map visual on the dataset US County Population [data source samples.us_counties]. It produces colored regions for the measurements that correspond to the state field.

  1. Start a new visual based on the US County Population dataset.
    For instructions, see Creating a visual.
  2. In the VISUALS menu, find and click Map.
    The shelves of the visual changed. They are now Geo, Color, Size, Drill, Tooltips, X Trellis, Y Trellis, and Filters. The only mandatory shelf for map visuals is Geo.
  3. Populate the shelves from the available fields (Dimensions, Measures) in the DATA menu.
    1. Under Dimensions, select stname and add it to the Geo shelf.
    2. Click the field to open the FIELD PROPERTIES menu, expand the Change Type option, and select the Geo Type State.
    3. Under Measures, select tot_pop and add it to the Colors shelf.
    4. Click the field to open the Field Properties menu, select Display Format,Category Integer, and select the thousands separator option. Click Save.
  4. Optional: Alias the field stname as State, and sum(tot_pop) as Population; see Alias.
  5. Optional: Enable panning and zooming option, as described in Customizing zoom.
  6. Optional: Change the color palette, as described in Change color palette of visuals.
  7. Click REFRESH VISUAL.
    The map visual appears.
  8. Click the pencil/edit icon next to the title of the visualization to enter a name for the visual.

    In this example, the title is changed to 'US State Population - Choropleth Map'. You can also add a brief description of the visual as a subtitle below the title of the visualization.

  9. At the top left corner of the Dashboard Designer, click SAVE.
