A tool to make animated IT schema ?

Ay,

I'm looking to add some IT schema to my Youtube videos to easily explain tech concepts but I don't really now which tool to use ?

I see lot of videos with animated schema and I'm wondering if Indie Hackers know some good tools to do that ?

Do you use or know any tool you could recommend ?

Important thing : I'm on Linux but I can use a Windows desktop if needed even if I prefer SaaS tools.

Thanks !
