Network

In Cloudera Data Visualization, Network visuals can be used to represent many systems and structures. The implementation is dynamic, with ongoing optimization adjustments that implement a force layout based on the Barnes–Hut approximation. It also includes many manual setting adjustments.

In the following example, the NCAA Basketball dataset is used for years 1985 through 2018.

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

  1. Start a new visual based on the NCAA Basketball dataset.
    For instructions, see Creating a visual.
  2. In the VISUALS menu, find and click Network.
    The shelves of the visual changed. They are now Nodes, Link Width, Link Color, Source Node Size, Target Node Size, Source Node Color, Target Node Color, Tooltips, X Trellis, Y Trellis, and Filters. There is only one mandatory shelf: Nodes, which adds two dimensions from the data menu to specify the start and end of each network connection in the plot.
    To learn more about the shelves of this visual, see Shelves for networks.
  3. Populate the shelves from the fields available in the DATA menu:
    1. Under Dimensions, select Team 1 and Team 2, and add them to the Nodes shelf.
    2. Under Measures, select Year and add it to the Filters shelf. Select the years 2015, 2016, and 2017.
    3. Add Round to the Filters shelf, and select 1.
  4. Click REFRESH VISUAL.
    The new network visual appears. You can see that this visual shows 1:1 pairing, because round 1 of play represents 1:1 elimination.
  5. To show the years separately, place the Year field on the Y Trellis shelf and click REFRESH VISUAL.
    The trellised version of the network visual appears.
  6. Change the title to Round 1, 2015-2017.

    • Click (pencil icon) next to the title of the visualization to edit it, and enter the new name.

    • [Optional] Click (pencil icon) below the title of the visualization to add a brief description of the visual.

  7. 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 'Round 1, 2015-2017'. You can also add a brief description of the visual as a subtitle below the title of the visualization.

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

To adjust the network display, check all the available settings for this visual.
