It's nuts you can't easily embed Looker charts into Google Slides. Google acquired them 4 years ago. If I search for "looker embed in google slide", most of what I see is about a company called "rollstack".
There's a couple of embedding startups out there -- I think there was one doing embedded analytics in our batch earlier on, but I don't remember if they pivoted. Looker is especially egregious in my opinion, since Google owns it.
Mostly, we think it's unhinged that companies spend so much cash on Snowflake/BQ/Looker and friends, not to mention the cost of hiring data engineers and data scientists, and then don't actually finish integrating it into the presentation layer.
