Overall Satisfaction with Google Charts
Google Charts is used across the whole organization to easily share basic charts in our presentations. We really like using a cloud-based solution, so we can collaborate more easily.
I use Google Charts in most instances, because our company loves being able to easily share slide decks with a shareable link on a cloud-based solution. Excel has much more functionality, but it's more difficult to update with a coworker (we have to email the presentation back and forth).
Google Charts is really great for simple visualizations that you want to collaborate with your peers on. More customization is difficult to implement.
