In this module you will learn how to use the Force-Directed Graph Power BI Custom Visual. The Force-Directed Graph allows you to display relationships between your data in a fun and interactive way.
Module 22 – Force-Directed Graph
- Power BI Custom Visual – Force-Directed Graph
- Dataset – Blog Visits.xlsx
- Completed Example – Module 22 – Force-Directed Graph.pbix
- Image – PersonIcon.png
- Shows relationships between different entities in your data.
- The width of the line that separate 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 number that are show 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.
