- Good visualizations can help people make sense of data sets that are too large to interpret by looking at the raw data. In this part you will learn to use a spreadsheet tool to make visualizations of your own.
There are many different kinds of charts that are used to visualize data. In this lesson, you will learn to make scatter, line, and bar charts, but there are many other types of visualizations that people use to interpret data in different ways. Look through the Data Visualization 101 Guide and familiarize yourself with the different chart types, paying particular attention to the scatter, line, and bar charts.
Disclaimer: This exercise is about using charts to explore trends in the data – not about creating the world's greatest chart. While the early parts of the lesson will walk you through very specific steps to make a particular chart, by the end of the exercise you will be creating your own customized charts to see what trends you can discover in the data.
