This is a most excellent place for technology news and articles.
I think most companies do have a M365 subscription. If you are in a corporate environment, you will likely have access to the services. But it is dumb that you need to be internet connected and paying for a subscription service in order to integrate python visualizations. Still sucks that Microsoft like every other tech company is just about nickel and diming their customers into oblivion.
