01 -  Slice the watermelon crosswise into a 1-inch-thick round slab. Pat dry with paper towels for best yogurt adhesion. 
 02 -  Place the watermelon round on a large cutting board or platter. 
 03 -  In a small bowl, mix the Greek yogurt with honey or maple syrup, if using. 
 04 -  Evenly spread the yogurt over the top of the watermelon, leaving a small border around the edge. 
 05 -  Arrange the sliced strawberries, blueberries, kiwi, and raspberries over the yogurt, distributing them attractively. 
 06 -  Sprinkle with shredded coconut and fresh mint, if desired. 
 07 -  Using a large knife, cut the topped watermelon round into 8 wedges, like pizza slices. Serve immediately for best texture and flavor.
