Data Visualization with Python
Contents
Introduction
Data visualization is the process of representing data in visual formats like charts, graphs, or maps to convey information quickly by revealing patterns and trends that may be difficult to discern when data is presented in tables or text formats. By turning complex data into visual elements, data visualization makes analysis more intuitive and accessible for everyone ultimately leading to more informed decision making processes.
To get into data visualization it is necessary to learn some fundamentals such as data formats and basic statistical figures that are commonly used.
Data visualization with Python
In Python, data visualization enhances statistical analysis by enabling the graphical representation of statistical summaries and distributions, such as histograms, box plots, and scatter plots. These visualizations help in assessing the distribution of data, identifying correlations, and detecting anomalies. Advanced visualizations, like heatmaps or pair plots, provide deeper insights into multivariate relationships and the impact of statistical measures such as correlation coefficients or regression lines.

Python Libraries for visualizing data
Python has become the language for data scientists and analysts due to its simplicity, versatility and robust ecosystem of libraries specifically tailored for data visualization purposes. These libraries offer tools for creating dynamic and interactive visualizations that cater to diverse needs. Below we present three main libraries:
- Seaborn: Seaborn is an extension of Matplotlib that focuses on statistical data visualization. It aims to make the creation of informative and visually pleasing graphics easier. With its user interface Seaborn allows users to generate visualizations using concise code.
