We've released the capacity to do this on Wiki with future proposals toward enablement on Issues. ### Description There are plenty of cases when diagrams should be attached to issues\wiki pages. Right now I'm creating a diagrams in external tools, and then exporting them as png file + xml, attaching them to issue to have an ability to collaborate. ### Proposal Integrate visual diagram editor. https://github.com/jgraph/draw.io and have an editor right in the GitLab. There is no need to add new markdown or learn new syntax, it's awesome frontend WYSYWIG editor. ### Links / references gitlab-ce#4048
