Arrowheads missing from connectors after Visio import

Problem

After importing a Visio chart into Mavim, connectors lose their arrowheads and appear as plain lines.

Solution

To restore arrowheads after import:

1. Right-click on the page background and select "Adjust relationships" from the context menu.
   
2. All connectors are selected:
   • If necessary, hold down the Ctrl key and click one by one on the lines you don't want to be modified.
3. On the right side of the screen, the Format shape panel appears. Set the desired arrow format here
   
4. All selected connectors will now display arrowheads again.
   
   
5. Click the save button in Visio to save the changes
