Ability to Do Visual Joins on Datasets Merged

What is the problem or goal the end user is trying to solve or accomplish?

Less technical users find it difficult to write SQL from scratch and do adhoc exploration in SQL lab. Filtering, sorting and aggregation are all available in the chart creation interface so adding the ability to join multiple datasets would round out those capabilities

What is the recommended solution by the Customer?

Add ability to join multiple datasets from the Explore interface by selecting multiple datasets and specifying the type of join. This will enable less SQL savvy users to do joins without writing SQL
