Notes on Data Visualization

• One of the most important (and least technical) skills in understanding data is asking good quetions. An appropiate question shares an interest you have in the data, tries to convey it to others, and is curiosity-oriented rather than math-oriented. Visualizing data is just like any other type of communication: success is defined by your audience's ability to pick up on, and be excited about, your insight.
• A proper visualization is a kind of narrative, providing a clear answer to a question without extraneuos details. By focusing on the original intent of the question, you can eliminate such details because the question provides a benchmark for what is and is not necessary.
