Importing Datasets

As promised, I wanted to share the rough flow that I've created in full. So it's attached here. It is by no means a full formed flow, it's missing a lot of the details for transforming data before importing (such as date transformations, etc). However, it's at a stage where I want to prototype it out and start iterating in code rather than in sketch.

Would love to hear what people think. Be harsh, be nice, any feedback is helpful.
