Data Visualization in R with ggplot2

Visualizing data effectively is one of the most critical skills in data analysis and reporting. This comprehensive text-based course guides you through transforming raw datasets into polished, insightful graphics using R and the industry-standard ggplot2 package. You will build a thorough understanding of the grammar of graphics, discovering how to map data attributes to visual properties, choose the right chart types, and structure clean plotting workflows for exploratory and explanatory analysis. What you'll learn: - Understand the core terminology and conceptual foundation of the grammar of graphics in R - Create common exploratory charts including scatter plots, line graphs, bar charts, histograms, and box plots - Apply aesthetic mappings like color, size, shape, and alpha to highlight multidimensional patterns - Customize themes, coordinate systems, scales, and typography for clear communication - Build multi-panel visual layouts using faceting techniques - Structure clean, reproducible plotting scripts aligned with modern tidyverse standards The course begins with foundational concepts, terminology, and data preparation basics before moving into practical code-driven plotting scenarios and real-world visualization patterns. This course is tailored for beginners, data analysts, and aspiring data scientists looking to communicate insights through code without requiring prior visualization experience.
