This course assumes no prior experience and can teach anyone how to use Python to analyze and visualize data. Stop using Excel and start harnessing the power of Python.

Data analysis is one of the hottest careers of the 21st century. As an analyst, your goal is to peel back layers of data in order to answer questions of interest; that is the power of analytics. It allows you to take raw data and create meaningful, actionable insights.

In this course, you’ll learn how to use Python, NumPy, SciPy, Pandas, and Seaborn to perform data analysis and visualization. You’ll explore the four crucial steps for any data analysis project: reading, describing, cleaning, and visualizing data. In each step, you will work with the most common and popular tools that data analysts use every day. By the end of the course, you will be able to confidently extract knowledge and answers from data.

Python Data Analysis and Visualization

# Introduction to scatter plots

First, let's take a look at **scatter plots.**

Scatter plots are great for plotting two variables to visualize how they might correlate and what relationship there might be between the variables.

As an example, look at the scatter plot below.

In this plot, we see a positive relationship between **Height** and **Diameter**. It is easy to see that relationship in a scatter plot by looking for points that are close to the 45-degree line pointing up and to the right.

This lesson explains what a scatter plot is, why it is used, and how to visualize data with scatter plot using Python libraries.
