Python libraries for Data Visualization

Here is a list of popular Python libraries for data visualization:

  1. Matplotlib: a plotting library for producing static, animated, and interactive visualizations. Matplotlib is a cross-platform, data visualization and graphical plotting library for Python and its numerical extension NumPy. It offers a viable open-source alternative to MATLAB and developers can use its APIs (Application Programming Interfaces) to embed plots in GUI applications [1, 3]. Matplotlib takes care of creating inbuilt defaults like Figure and Axes, where a figure object can be considered as a box-like container that can hold one or more axes [2].
  2. Seaborn: a library based on Matplotlib that provides a high-level interface for statistical graphics. Seaborn is a data visualization library in Python that is built on top of Matplotlib. It provides a high-level interface for creating attractive and informative statistical graphics and is considered as an extension of Matplotlib [1, 2].
  3. Plotly: an interactive, browser-based graphing library for creating complex, publication-quality visualizations. Plotly is an open-source library for data visualization in Python. It supports various types of plots including line charts, scatter plots, histograms, and bar charts. It is an interactive, browser-based graphing library that is built on top of plotly.js [1, 2, 3].
  4. Bokeh: an open-source library for data visualization in Python. It allows users to create interactive, web-based visualizations that are easy to deploy in modern web browsers. The library is designed to provide high-level abstractions for complex data visualizations, making it easy for users to create advanced visualizations with ease. Bokeh also provides a number of tools and widgets that allow users to interact with the data in their visualizations, making it an ideal choice for data-driven applications.
  5. ggplot: a data visualization library for the programming language R. It is based on the Grammar of Graphics, a theoretical framework for creating visualizations that separates the components of a graph into a systematic, organized structure. With ggplot, users can create a wide range of statistical graphics, including bar charts, histograms, scatter plots, and more. The library is highly customizable and is known for its ability to create beautiful, publication-quality graphics.
  6. Pygal: a Python library for creating dynamic and interactive visualizations using Scalable Vector Graphics (SVG). It provides a simple yet powerful interface for creating various types of charts, including bar charts, line charts, area charts, histograms, and more. Pygal allows users to customize their visualizations in terms of colors, labels, legends, and more, to effectively communicate insights from their data.
  7. Geoplotlib: a library in Python that is used to create visualizations of geographical data. It provides a high-level interface for creating maps and plots, which can be easily customized according to the user’s needs. Geoplotlib supports a wide range of geographical data formats, making it a versatile tool for visualizing location-based information.
  8. Altair: a data visualization library for Python, which is built on top of the Vega-Lite visualization grammar. It allows users to declare the visualizations they want to create using a simple and concise syntax. The library then takes care of generating the underlying Vega-Lite specifications that describe the visualization, which are then rendered as interactive visualizations in the browser. Altair is designed to support a wide range of statistical visualizations, including bar charts, line plots, scatter plots, histograms, and more, and it provides an easy-to-use interface for specifying the data, scales, and encoding of the visualization.

These libraries offer a range of features and styles, so the best choice for your needs may depend on the specific problem you’re trying to solve.

Here are some examples of data visualization provided by the Python libraries:


import as px
import pandas as pd

df = pd.DataFrame({'x': [1, 2, 3, 4], 'y': [5, 6, 7, 8], 'z': [9, 10, 11, 12]})
fig = px.scatter(df, x='x', y='y', color='z', size='z', title='Plotly Visualization')
Plotly Scatter Plot


from bokeh.plotting import figure, show
from bokeh.models import ColumnDataSource
from import output_notebook


source = ColumnDataSource(data={'x': [1, 2, 3, 4], 'y': [5, 6, 7, 8]})
p = figure(title='Bokeh Visualization')'x', 'y', source=source)


import seaborn as sns
import matplotlib.pyplot as plt

# Load the example tips dataset
tips = sns.load_dataset("tips")

# Create a scatterplot of total bill amounts versus tip amounts
sns.scatterplot(x="total_bill", y="tip", data=tips)

# Add title to the plot
plt.title("Total Bill vs. Tip Amount")

# Show the plot
Seaborn Scatter Plot

Here are some tips for beginners in data visualization:

  1. Start with the basics: Learn about data structures and common plotting functions, such as bar plots, line plots, scatter plots, etc.
  2. Use sample datasets: Start by visualizing simple and well-known datasets, such as iris, titanic, and mpg, to get a feel for the data and see what kind of insights you can extract.
  3. Choose the right visualization type: Different types of visualizations are better suited for different types of data and insights. Choose the right one for the task at hand.
  4. Keep it simple: Begin with basic visualizations and gradually add complexity as you gain more experience and confidence.
  5. Experiment with different libraries: Try out different visualization libraries to see which one works best for your needs.
  6. Follow the rules of visual perception: Keep in mind the rules of visual perception when creating visualizations, such as color contrast, font size, and labelling, to make your visualizations clear and understandable.
  7. Learn from others: Look at the visualizations created by experts in your field, and try to understand how they were created and what insights they were trying to communicate.
  8. Practice, practice, practice: The more you practice, the better you will get at creating effective and compelling visualizations.
