Data Visualization
Data Visualization is used to communicate information clearly and efficiently to users by the usage of information graphics such as tables and charts. It helps users in analyzing a large amount of data in a simpler way. It makes complex data more accessible, understandable, and usable.
Tables are used where users need to see the pattern of a specific parameter, while charts are used to show patterns or relationships in the data for one or more parameters.
