Ask HN: Recommendation for data pipeline / stack diagram tool?

Hi, we’re needing to prepare some sketches of data assets and link them visually to show data flow.

It’s for a simple presentation / pitch deck, so we’re specifically looking for a diagramming tool with nice graphics (as opposed to something feature-rich).

Any recommendations would be appreciated (don’t mind if it’s a paid product, provided there’s a free trial we can use to assess).

Thanks! ^_^
