I have found this tool, that let your generate a beautiful image from your Azure function to document them.

Be aware that the tool require Nodejs 10 !

In order to produce it, you need:

• to have installed globally Azure Function Core Tools

npm i -g azure-functions-core-tools

• to clone the tool in the directory of the function, and execute the following commands

npm install
npm run build
func start

You whould go to http://localhost:7071/ and see the following screen.

The tool will ask a github repo or a local path to document your Function. It will work with C# Azure Function.

Edit:
this is now available through a vscode extension : durablefunctionsmonitor.durablefunctionsmonitor

Hope this helps !
