The office is an integral part of every company where various business activities take place and various key business decisions are made. The office is also a center for processing business data and business information. Office operations represent a set of rules and measures in dealing with office files and documents, their receipt and issuance, as well as records and delivery of files and documents to work for processing, use, preservation and submission to the competent archive. Data is a set of characters, letters or numbers that are written on a certain medium, for example on paper, film, magnetic media, etc. There are several categories of data such as data by nature, data by source, data by time collection and data based on retrieving. Each of these categories represents a specific type of data. Data management methods are data storage, data visualization and data mining. Data visualization is an interdisciplinary field and one of the methods of data management that deals with graphic and pictorial representations of data and information. There are two basic types of data visualization if they are tabular and graphical data visualization. Techniques for graphical data visualization are as bar, circle and ring diagrams, as well as networks and maps. Software tools for data visualization are used to collect a new and fresh set of data from different data sources and convert the data into results displayed using different techniques and forms of graphical representation of the relationship between two or more qualitative, and more often quantitative, data. There are two types of software tools, free and commercial. There are as many as 15 examples of software tools for data visualization. Libraries for data visualization represent a solution when it is necessary to create more complex forms of data visualization. The libraries are used for the user to develop, implement and test program code and a group of program codes on different code editors, which automatically perform correctness checks when starting the local server and display the diagram implemented by the program versions of the code on the local server.
