What is data visualization?

Data visualization is a way of presenting data in a visual context. With data visualization, you can communicate a large amount of information clearly and concisely. You can also observe patterns and trends you might might miss if you only examined the raw data (ex. Ascombe's Quartet).

Why visualize data?

• Visualizations can help groups achieve more insight into the nature of a problem and discover new understanding;
• Great visualizations create a shared view of a situation and align folks on needed actions;
• Efficiency!
