Chord diagrams show directed relationships among a group of entities using colored lines (chords); this allows for an easy representation of correlating data. If you want to learn more about Power BI Custom Visuals, [view my previous blog posts](https://blog.pragmaticworks.com/topic/power-bi-custom-visuals).

### Key Takeaways

*Selecting a data category will also cross filter any other visualizations in the report.*

- Under the **Format** paintbrush there are some options that are helpful with customizing the appearance of the Chord chart.
- The **Data colors **section gives you the ability to change the **Default color values** on the chart.  You can also turn on **Show all** and provide specific colors you would like to see on each category of the Chord.
