How to create legends like these legends? In my case, if I should make the 'Node size' legend, then I would make the some nodes and mapping 'Node size' for size difference. And, for text describing the legend, I would 'Add annotation-text annotation'. So, I would drag text annotation, and put annotation into appropriate position. Then, I could not set perfect parralel with all of annotations. So, I want to set annotation perfectly parralel like pictures, so how to make the legend? Use only Legend Creator? Or, Node Label style? I don't now how to do!
