How Do You Teach Data Visualization?

At gogal, we were developing an internal training programme. i got asked to develop content on data visualization. So this was always a space that i'd enjoyed. And when i think o back to my teamif people would come to me with questions or to brain storm. I became sort of the defacto person on our team when it came to date a visualization but it was when we were building out this programme that i got the opportunity to pause and do some research.
