CDP Data Visualization enables you to create Treemap visuals. Treemaps display hierarchical data as a set of nested rectangles. Each 'branch' of the tree is a rectangle that corresponds to a particular dimension, with smaller rectangles that represent secondary dimensions. All rectangle areas are proportional to the aggregate measure that corresponds to the dimension.

Using color and size dimensions in the tree structure often brings to light new insights and correspondence patterns. Because of the highly efficient use of space, treemaps legibly display very large number of items simultaneously.

In the following example the NYC Taxi Trips dataset is used, which is based on the data in the ny-trips.csv file.

For an overview of shelves that specify this visual, see Shelves for treemaps.

  1. Start a new visual based on the NYC Taxi Trips dataset.
    For instructions, see Creating a visual.
  2. In the VISUALS menu, find and click Treemap.
    The shelves of the visual changed. They are now Dimensions, Measure, Tooltips, X Trellis, Y Trellis, and Filters. The mandatory shelves are:
    • Dimensions: specify one or two dimensions to define the branches and leaf nodes of the treemap.
    • Measure: specifies one measurement that determines the area of the leaf node.
  3. Populate the shelves from the available fields (Dimensions and Measures) in the DATA menu.
    1. Under Dimensions, select Pickup Boro and Pickup Neighborhood, and add them to the Dimensions shelf, in that order.
    1. Under Measures, select Record Count and add it to the Measure shelf.
    The new treemap visual appears.
  5. 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 'NYC Taxi - Treemap'. You can also add a brief description of the visual as a subtitle below the title of the visualization.

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