Draw diagrams from markdown within ReDoc page

I have discovered needs to embed various diagrams within the documentation page rendered by the ReDoc. Currently I generate pictures from PlantUML text and hope to refer to these pictures from the markdown text embedded within the swagger specification, provided to the ReDoc. The problem is that the pictures need to be saved and served from somewhere and could get dis-synchronized with the documentation eventually, because the documentation content ends up in different places.

Instead, it would be great to have a way to render diagrams within the ReDoc page from markdown text embedded within the swagger specification. Something similar to this: http://support.typora.io/Draw-Diagrams-With-Markdown/

Is it valid idea? or I am taking some non-advised approach? If valid, would this feature be possible for implementation?

Start by reviewing how markdown embedded in the Swagger/OpenAPI specification is rendered within a ReDoc page, along with the proposed PlantUML-style diagram syntax. Define how diagrams should be represented and rendered without externally stored images, then verify that the resulting documentation stays synchronized with the specification.
