I know that descriptors are not included in the graph. But I think it would be more convenient if we did the following -
Instead of just not showing descriptors, we can add the title over the descriptors.
I think I know why the creators don’t show the descriptors. It may be because graph is more of a conceptual view, (i.e. concept heavy, rather than information heavy).
But, I think this suggestion, can help create better mind maps
The creators can give an option to show descriptors, which may be kept off by default. But by doing this, they can give an option to the user to design their graphs the way they want
