Key Takeaways

  • Shows relationships between different entities in your data.
  • The width of the line that seperates each entity represents the strength of the relationship.

This Force-Directed Graph shows visitors to my blog and their next likely step after visiting my home page.

  • Under the Format paintbrush there are several settings that allow you to customize the way data is presented in the Force-Directed Graph.
  • Under the Data labels section you can you can choose to increase the text size, or change the color of the text, by using the Fill and Text Size properties.

  • The Links property defines how the relationship lines will appear between each entity.
    • Turning on the Arrow property allows you to see the direction of the relationship.
    • Changing the Label property to On adds data labels on each arrow so you know the number that’s represented by the line.
    • The Color property allows you to define the color of the lines dynamically based on the data.
    • Turning off the Thickness property will make it so that each line is the exact same size, regardless of the strength of the relationship.
    • Using Display Units and Decimal Places allows you to adjust the formatting of the numbers that are shown when the Label property is turned on.

  • Under the Nodes section you can adjust the way each end point of the relationship is visualized.
    • By turning on the Image property it will allow you to use an image instead of the default representation of an entity.
    • In this example, we used the following Image URL to modify what an entity is represented as: https://file.ac/j9ja34EeWjQ/PersonIcon.png

  • Adjusting the Charge property under the Size section allows you to adjust the amount of space that the visual takes up on the design surface.

  • In addition to these properties, you have a set of settings that appears on every visual to adjust the background color, add a border around the visual and lock the aspect ratio.
