We want each point on the scatter plot to be sized based on the number of people in the group, with larger groups having bigger points on the plot. Here, we're creating a scatter plot of total bill versus tip amount. The first customization we'll talk about is point size. Use with both scatterplot() and relplot() Show relationship between two quantitative variables For the rest of this post, we'll use the tips dataset to learn how to use each customization and cover best practices for deciding which customizations to use. All of these options can be used in both the "scatterplot()" and "relplot()" functions, but we'll continue to use "relplot()" for the rest of the course since it's more flexible and allows us to create subplots. In addition to these, Seaborn allows you to add more information to scatter plots by varying the size, the style, and the transparency of the points. We've seen a few ways to add more information to them as well, by creating subplots or plotting subgroups with different colored points. Seaborn will do the rest.So far, we've only scratched the surface of what we're able to do with scatter plots in Seaborn.Īs a reminder, scatter plots are a great tool for visualizing the relationship between two quantitative variables. Similarly to before, we use the function lineplot with the dataset and the columns representing the x and y axis. It is a popular and known type of chart, and it’s super easy to produce. This plot draws a line that represents the revolution of continuous or categorical data. Very easy, right? The function scatterplot expects the dataset we want to plot and the columns representing the x and y axis. sns.scatterplot(data=flights_data, x="year", y="passengers") Creating a scatter plot in the seaborn library is so simple and with just one line of code. All these datasets are available on a GitHub repositoryĪ scatter plot is a diagram that displays points based on two dimensions of the dataset. head ()Īll the magic happens when calling the function load_dataset, which expects the name of the data to be loaded and returns a dataframe. Let’s then install seaborn, and of course, also the package notebookįlights_data = sns. When installing seaborn, the library will install its dependencies, including matplotlib, pandas, numpy, and scipy. Installing seaborn is as easy as installing one library using your favorite Python package manager. It abstracts complexity while allowing you to design your plots to your requirements. Seaborn works by capturing entire dataframes or arrays containing all your data and performing all the internal functions necessary for semantic mapping and statistical aggregation to convert data into informative plots. Seaborn design allows you to explore and understand your data quickly. It builds on top of matplotlibĪnd integrates closely with pandas data structures Is a library for making statistical graphics in Python. If you want to follow along you can create your own project or simply check out my seaborn guide project In this article, we will focus on how to work with Seaborn to create best-in-class plots. Seaborn is as powerful as matplotlib while also providing an abstraction to simplify plots and bring some unique features. However, some actions or customizations can be hard to deal with when using it.ĭevelopers created a new library based on matplotlib called seaborn. It is its level of customization and operability that set it in the first place. Matplotlib is probably the most recognized plotting library out there, available for Python and other programming languages like R. Many great libraries are available for Python to work with data like numpy, pandas, matplotlib, tensorflow. There are many reasons why Python is the best choice for data science, but one of the most important ones is its ecosystem of libraries. Though more complicated as it requires programming knowledge, Python allows you to perform any manipulation, transformation, and visualization of your data. However, when working with raw data that requires transformation and a good playground for data, Python is an excellent choice. They are very powerful tools, and they have their audience. There are many tools to perform data visualization, such as Tableau, Power BI, ChartBlocks, and more, which are no-code tools. Charts reduce the complexity of the data and make it easier to understand for any user. Data visualization is a technique that allows data scientists to convert raw data into charts and plots that generate valuable insights.
