Networks

CDP Data Visualization Network visuals may be used to represent many systems and structures. Our 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.

1. Start a new visual based on dataset NCAA Basketball; see Creating a visual.
2. In the visuals menu, find and click Network.

   

   

3. Note that 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: Add 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 network visuals.

4. Populate the shelves from the available fields 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.

      Similarly, add Round to the Filters shelf, and select 1.

5. Click Refresh Visual.

   

6. The new network visual appears.
