Low-End Visualization Techniques for Meteorological Data Analysis

This document presents an overview of low-end visualization methods developed by the PRISM WP4a team, aimed at enhancing meteorological data representation and analysis. It outlines the objectives for generating standard plots for quality control, model comparisons, and presentations. Key topics include a comparison between low-end and high-end visualization, layout structures, display parameters, and practical examples such as isolines, iso-fills, and vectors. Additionally, it addresses existing challenges and potential integrations with other systems, highlighting the goal of creating accessible visualization tools.
