Principles
The right chart for the right purpose. Each way you look at data will tell you a different story. Finding the right angle of data presentation is key to convey the right information leading to the right decision. Given the goal of your users, you need to pick the right type of representation.

Do not use color to make your chart pretty. Use color to make information stand out from your data and make sure to use one color per data. Keep accessibility in mind and do use contrasting shades to maximize readability.
