Description: Provides a comprehensive suite of tools for processing,
    analyzing, and visualizing hydrochemical data in a reproducible and
    programmatic workflow. Implements unit conversion, censored data
    management, ionic balance calculation, water type classification, and
    a range of hydrochemical indices relevant to water quality assessment.
    Offers advanced visualization functions for generating

    and ternary diagrams — the standard
    graphical tools used in hydrochemical interpretation.  Unlike existing
    solutions that rely on spreadsheets or proprietary graphical software,
    'hydrochem' is designed for scalability and reproducibility, lowering
    the technical barrier for hydrochemists working with datasets of
    varying complexity. It integrates seamlessly into modern R workflows
    and supports rigorous water resource management and research.
