Data visualization is the graphical representation of data and information. It involves
creating visual representations, such as charts, graphs, and maps, to communicate
complex information and patterns in a clear and concise way. The goal of data
visualization is to help people understand and make sense of large and complex
data sets, which may otherwise be difficult to interpret.
Data visualization is used in a wide range of fields, including business, science,
engineering, finance, and social sciences. It can be used to identify trends, patterns,
and relationships in data, to compare and contrast data sets, and to present insights
and conclusions in a visually compelling way. By presenting information in a clear
and accessible way, data visualization helps people make informed decisions and

take action based on the insights they gain from the data.
