Introduction to Data Visualization

In today's fast-paced world, the amount of data continues to grow. Plotting helps turn raw data into insightful visualizations, making it easier to understand the information that matters.

Main applications of plotting are the following:

• Communication: plotting helps convey complex ideas and information to a wide range of audiences;
• Analytics: helpful providing a clear overview of data distribution, relationships, and correlations;
• Decision making: instrumental in creating reports and dashboards that assist in strategic decision-making.
