I want to import data from excel and make a hierarchical graph but when I import it the font size of all the node labels is too small. Then when I change the font using the font setting in the right bottom corner all the arrows get messed up. I was wondering if there was a way of specifiying the font size before generating the graph so that the graph that is generated is according to ths font size. That way none of the nodes or arrows would need to be re-adjusted
