Thanks yuhuisg, I have raised this in the Ideas section - https://experienceleaguecommunities.adobe.com/t5/adobe-analytics-ideas/wrap-labels-on-by-default-on-flow-visualization/idi-p/540465/highlight/true 

Everytime I use the Flow visualization I have to click on Wrap labels so I can actually see the full page name! Is there way that this can be turned on by default so I don't have to click it all the time? Anyone else get frustrated by this?
