I. Introduction
In the domain of power system monitoring and assessment, offline engineering analysis tools have emerged as invaluable aids for a variety of crucial tasks. These tools serve diverse purposes, ranging from identifying events to confirming models, adjusting settings, ensuring adherence to regulations, and establishing reference points for different power system aspects such as angle deviations and oscillations. The significance of these tools cannot be overstated, as they form the foundation for upholding the dependability, effectiveness, and steadiness of power systems. In the pursuit of advancing power system monitoring and analysis, a notable avenue of exploration lies in creating Graphical User Interface (GUI) powered tools. Such tools have the potential to transform the accessibility and usability of intricate analytical processes by offering an intuitively visual platform for users [1], [2]. These tools come in two primary forms: those based on desktop applications [3], and those accessible through web browsers. The latter option, web-based applications, holds particular promise due to its adaptability and ease of use.
