Project General Description

The visualization tool that assists the tax authority's work enables the effective exploration and analysis of complex relationships between taxpayers. This modern, graph-based solution utilizes Cytoscape technology and is accessible via a JavaScript-based web interface. The tool not only displays the relationships among taxpayers but also integrates with the e-invoice system, providing a more comprehensive view of taxpayer networks than ever before.

Challenge

The central element of the Network Visualization Tool is the graph-based representation provided by the Cytoscape library. This advanced technology allows for the intuitive and dynamic depiction of relationships among taxpayers, where individual taxpayers are represented as nodes and the connections between them as edges.

The tool is capable of displaying complex relationships such as ownership structures, business partnerships, and even patterns of suspicious transactions. This comprehensive analytical capability significantly enhances the effectiveness and accuracy of tax audits.

During the development of the Network Visualization Tool, special attention was given to meeting user needs at a high level. The design and implementation of the application were carried out in close collaboration with end users, namely tax auditors and other experts, to ensure maximum usability and efficiency of the system.
