The Data Visualization System is a desktop-based application developed to simplify the process of understanding complex datasets through intuitive and interactive visual representations. Built using Java and data visualization libraries such as J-Free Chart, the system enables users to transform raw numerical or categorical data into meaningful charts and graphs including bar charts, pie charts, line graphs, and scatter plots.
This project addresses the need for a user-friendly, offline-capable visualization tool for students, researchers, and professionals who need quick insights from data without relying on internet connectivity or expensive software. It features CSV import support, manual data entry, dynamic chart updates, and export options for generated visuals.

The system aims to empower users to detect patterns, trends, and outliers at a glance, thereby improving decision-making and reporting efficiency. By offering a modular and extensible design, the project lays the groundwork for future enhancements such as real-time data streaming, dashboard creation, and integration with external databases.
