I echo what a lot of the others say. It looks like OP you are making a dataset for fair pay, definitely a cool move. I’ll peep the fit.

As a viz though, this falls flat. I came to the wrong conclusion just looking at it. The legend needed to be bigger. Also if this phased through the worker types in a sort of slide show, that might’ve been more effective then the current state.

Like everyone is saying too, the time horizon distorts how I view the data.

I think this is a wonderful dataset, but definitely a viz that can be flipped to be more powerful.
