4 core competencies to discover the next level of data visualization in Python

Python is one of the most versatile programming languages in the world. You can use it in many industries, including data science and analytics. This blog post will discuss four core competencies that you need to reach the next level of data visualization with Python. With these skills, you will create stunning visualizations that will help you understand your data better!

According to the statistics report, "Python is one of the most widely utilized programming languages among developers worldwide in 2021."

Here are the four core competencies to discover the next level of data visualization in Python:

Understand the data

Before you visualize a particular dataset, first understand that dataset using various statistical analysis techniques such as mean, median, and mode. It will help you identify outliers in your data that might affect your subsequent visualization results. If there are too many outliers, perform outlier removal before creating any chart or graph to get an accurate result.

Once you understand the data, it's time to explore and visualize it. You can use various plotting libraries such as Matplotlib, Seaborn, and Bokeh for data visualization in Python. So choose the suitable library for the task at hand.

Visualize the data

The main goal of data visualization is to make it easier for the human brain to understand complex datasets. So when you are visualizing a dataset, always focus on how well your graphs or charts can convey the message that they are trying to portray. 

Data visualization is an art, and there are no hard-and-fast rules for creating perfect graphs or charts. But following some standard best practices can help you make more effective visualizations. Here are a few tips:

  • Use colors wisely
  • Keep your charts simple
  • Use legends and labels effectively

Analyze the data

After creating a few visualizations, it's time to analyze that data. It is where your knowledge of statistics and data analysis comes in handy. Look for trends and patterns in the data and identify any underlying relationships.

Refine and improve

Once you analyze the data, it's time to refine your visualizations. It might involve tweaking the colors, fonts, or layout of your graphs and charts. You might also need to change the type of visualization depending on the insights you have gained from your analysis.

Always be prepared to iterate on your data visualizations and keep refining them until you are happy with the results.

Now that you know the four core competencies, it's time to put them into practice and discover the next level of data visualization in Python.
