Graphical as in integrated with the normal editing view? There's a new very nicely done one for Emacs: https://github.com/svaante/dape . The documentation about using it is currently a bit terse though.
I actually don't mind if it's not integrated with the editor. I'm fine with a debugger being a standalone application. What I want is the ability to see the source, set breakpoints and navigate the code efficiently inside the debugger. vscode is currently the best option for this remotely
