Let’s set aside technical considerations and just explore a few unorthodox data visuals. Why? Because doing so helps us to reward viewers eye’s and brains.

Without support from I.T., analysts increasingly need to perform data preparation tasks of varying complexity in order to wrangle data into shape for current analytic needs. Using Alteryx Designer, many such tasks are simple and intuitive. Let’s consider an example.
