Making a count plot with a DataFrame

In this exercise, we'll look at the responses to a survey sent out to young people. Our primary question here is: how many young people surveyed report being scared of spiders? Survey participants were asked to agree or disagree with the statement "I am afraid of spiders". Responses vary from 1 to 5, where 1 is "Strongly disagree" and 5 is "Strongly agree".

To get you started, the filepath to the csv file with the survey data has been assigned to the variable csv_filepath.

Note that because csv_filepath is a Python variable, you will not need to put quotation marks around it when you read the csv.

Istruzioni dell'esercizio

Import Matplotlib, pandas, and Seaborn using the standard names.
Create a DataFrame named df from the csv file located at csv_filepath.
Use the countplot() function with the x= and data= arguments to create a count plot with the "Spiders" column values on the x-axis.
Display the plot.

What is Seaborn, and when should you use it? In this chapter, you will find out! Plus, you will learn how to create scatter plots and count plots with both lists of data and pandas DataFrames. You will also be introduced to one of the big advantages of using Seaborn - the ability to easily add a third variable to your plots by using color to represent different subgroups.

In this chapter, you will create and customize plots that visualize the relationship between two quantitative variables. To do this, you will use scatter plots and line plots to explore how the level of air pollution in a city changes over the course of a day and how horsepower relates to fuel efficiency in cars. You will also see another big advantage of using Seaborn - the ability to easily create subplots in a single figure!

Categorical variables are present in nearly every dataset, but they are especially prominent in survey data. In this chapter, you will learn how to create and customize categorical plots such as box plots, bar plots, count plots, and point plots. Along the way, you will explore survey data from young people about their interests, students about their study habits, and adult men about their feelings about masculinity.

In this final chapter, you will learn how to add informative plot titles and axis labels, which are one of the most important parts of any data visualization! You will also learn how to customize the style of your visualizations in order to more quickly orient your audience to the key takeaways. Then, you will put everything you have learned together for the final exercises of the course!
