Python, a popular programming language for data analysis and machine learning, offers a range of powerful data visualization tools & techniques.
Data visualization is the process of representing data and information in a graphical or visual format. It involves creating visual representations of data to help people better understand and interpret information. The goal of data visualization is to make complex data easier to understand, analyze, and communicate. It allows individuals to quickly identify patterns, trends, and outliers in data, which can lead to better insights and decision-making.
Data visualization techniques can take many forms, including charts, graphs, maps, and diagrams. For example, line charts are often used to show trends over time, while bar charts are used to compare different values or categories. Maps can be used to represent geographical data, and diagrams can be used to show relationships or hierarchies between different data points.
