Here’s another installment of my round-up. All of these links are taken from Dataquest’s Data Science online course.
- Tableau’s Color Blind 10, although discontinued, is a great color palette to utilize, since grays are perfect for non-data ink, while the different blues and oranges provide nice contrasts for highlights.
- Tidy Data as an organizing principle is something that I’d like to go back to later in my development. At its philosophical core:
- Tidy datasets are easy to manipulate, model and visualize, and have a specific structure: each variable is a column, each observation is a row, and each type of observational unit is a table. (Hadley Wickham)
- RegExr seems like a valuable tool in learning and mastering regular expressions in a very visual way.
- Simon Holywell’s The SQL Style Guide has a few quite eye-opening tips, such as using collective names for tables and singular names for columns, and lining up root keywords to form a code river. Way to make things incredibly legible, almost sculptural. Also, extra points for referencing typographical quirks in the explanation.
