Data visualization is the graphical representation of information and data using visual elements like charts, graphs, and maps to provide an accessible way to see and understand trends and patterns in data. It allows massive amounts of information to be analyzed and data-driven decisions to be made. Data visualization tells a story by removing noise from data and highlighting useful information. Common types include charts, graphs, maps, and infographics, with tools ranging from simple online options to more complex offline programs. The key is to focus on best practices and developing a personal style when creating visualizations.
