Before we embark on an analytics project, we often already have some questions that we want to get answered quickly from visualizations. These visualizations, which answer different questions, may be packaged as a dashboard or may be used as, and when, needed. We will also start with some questions and try to build visualizations to get answers to those questions.

We will try to answer the following questions:

• How does the average temperature change over time?
• How does the average humidity change over time?
• How do temperature and humidity change at each location over time?
• Can I visualize temperature and humidity over a map?
• How are the sensors distributed across departments?

Let's build visualizations to get the answers, starting with the first question.
