Hi!
I wanted to generate a dependency graph for mn mnemonic but cargo-graph gives me the error
File { fd: 3, path: "/home/swym/tmp/mnemonic/Cargo.toml", read: true, write: false }:11:1-11:8 duplicate key: version
I failed to find a duplicate version key manually and also tomlcheck confirms that Cargo.lock seems fine.
gh won't let me attach Cargo.lock but you should be able to reproduce by git cloning mnemonic...
