I'm looking for an app to draw diagram

Hello 😊 Do you have in mind an android app that allows you to make diagrams?

Even something simple that lets you edit and view text graph like mermaid.js.org or other text format.

And if it's possible to integrate these tools with markdown notes that would be huge!!!! 🤗🤗🤗

Thanks for your boosts and answers!

For exemple on desktop I use draw.io or zettlr.com
