Currently we have a nice table at
https://dlang.org/spec/const3.html#implicit_conversions
documenting how implicit conversions work across qualifiers.
While complete and informative, it doesn't quickly give an
intuition.
A DAG like the sketch at http://imgur.com/a/VuxLT would be easy
to follow - all paths are possible conversions.
What would be a nice tool to render this DAG online? Who'd want
to work on inserting this? Ideally it would be some vector
rendering.
Thanks,

There's also mermaid. They have a live editor here:

You can view the diagram here:

The syntax to create the given graph would be:
graph BT
%% Declare Nodes With Spaces in their Name
inout_const[inout const]
shared_const[shared const]
inout_shared_const[inout shared const]
inout_shared[inout shared]
%% Left hand side of graph
mutable --> const
inout_const --> const
inout --> inout_const
immutable --> inout_const
%% Right hand side of graph
immutable --> inout_shared_const
inout_shared --> inout_shared_const
shared --> shared_const
inout_shared_const --> shared_const
