*This Flow Map displays the migration movement from one county to another in the state of Florida.*

- Under the **Format** paintbrush you will find there are several customizations that you can enable.
- In the **Visual style **section you can modify the type of map that is being used and when you select Flow you can group lines together to make the data easier to view.

- Under the **Legend** section you can modify how and where the legend appears.

- Using the **Color** section you can change the color of the lines. In this scenario, I used the Autofill option to prepopulate the colors for me.

- The **Width** property can be used to adjust the width of the lines between each point.

- Modifying the **Bubble** section will change how the bubbles appear above each point. You can even add a label to the bubbles here.

- The **Detail format** section will allow you to modify how the bubble labels will appear.

- Modifying the **Map control** will allow you to change the type of map that is shown, as well as adjusting the pan, zoom and auto fit interaction.

- With the **Map element** feature you can turn on or off several map elements that may be useful to your solution.

- Under the **Advanced** section you can turn on/off the visual caching. This is helpful to keep on so the report doesn’t have to re-render all the data points every time the report is opened. The Relocate feature allows you to move a geocoded spot to another location.

You can also adjust the background color, add a border around the visual and lock the aspect ratio under the Format section.
