This is just a proposal.
I developed same kind of tool to visualize contracts.
solidity-visualizer generates reports for inheritance and use relations among contracts like surya, however
this report contracts can be draggable unlike dot file.
And this is compatible to truffle project by just one command.
If you think these characteristics are advantages, I can add these to surya.
