Support depgraph responses?

[ropnop]

Hello! Is it on the roadmap to support JSON responses from the depgraph API? We use the depgraph API in our CI pipelines with a custom Bazel rule, but the responses are difficult to read in CI logs when it's just JSON output. HTML reports would be very nice, and I started looking into it before I found this project. Wanted to check before we go too far in writing our own reporting tool. Thanks!
