DWD Frontend React Design Documentation

Architecture Overview

DWD Frontend React is a modern web application built with React that provides a user interface for the Digital Water Distribution (DWD) suite. It offers interactive visualization of water distribution networks, simulation results, and analytical tools through various map views and data visualizations.
