It is reported that up to 80% of data analysts time is dedicated to data preparation. I will present a review of current visual methods and tools for data preparation using interactive visualizations. Such tools have become very popular and become industry standards (e.g. Data Wrangler lead to Trifacta https://www.trifacta.com/ and has a $750M estimated valuation). However, so far the main focus has been on tabular-like data; I will also discuss how to cope with more complex data structures preparation (e.g graphs, streaming data, etc.) and present recent research in this area.
