Harness the full potential of your data through powerful visual storytelling with R and GGPlot2. This course from Geo-ICT teaches you to turn complex data into clear, engaging visuals that reveal insights and drive informed decisions.
In today’s digital world, data is everywhere—but raw data alone isn’t useful. To make sense of it and share your insights with others, you need to visualize it. That’s where data visualization comes in. It helps you find patterns, highlight trends, and turn complex datasets into clear, impactful visuals that people can actually understand.
Whether you’re tracking business performance, monitoring health trends, or exploring geographic data, good visualizations make your work easier to understand—and much more persuasive. The ability to “see” what’s happening in your data can make all the difference when you’re trying to tell a story, solve a problem, or make an informed decision.
R, one of the most popular programming languages for data analysis, is built for this kind of work. And within R, the ggplot2 package is a powerful tool for creating professional, high-quality charts and graphs. Based on the “Grammar of Graphics,” ggplot2 lets you build visuals layer by layer, giving you full control over every detail. It’s flexible, smart, and widely used by data professionals around the world.
At Geo-ICT, we’ve designed this course to help you unlock that power. You’ll learn how to build beautiful, insightful visualizations that not only look good but also communicate your message clearly. Whether you’re new to data or looking to sharpen your skills, this course will give you the tools to stand out.
This course gives you a hands-on introduction to data visualization using R and ggplot2. You’ll start with the basics—learning how to install and set up R, understand tidy data structures, and use tibbles (a cleaner, more user-friendly version of data frames in R). From there, you’ll build simple plots like bar graphs and scatter plots, then move on to more advanced visuals like boxplots and faceted graphs.
Along the way, you’ll get comfortable with ggplot’s layer-based structure. You’ll learn how to use geometries (like points, lines, and bars) and map aesthetics (such as color, shape, and size) to create visuals that are both accurate and visually appealing. You’ll also discover how to adjust plot elements like titles, labels, axes, and legends to make your message even clearer.
But making great visuals isn’t just about plotting—it’s also about having clean, well-structured data. That’s why we also teach you how to use the dplyr and reshape2 packages to filter, sort, group, and reshape your data. These tools help you prepare your data before you ever touch a graph, so your visuals are based on solid, well-organized information.
Finally, you’ll apply everything you’ve learned to real-world scenarios. Whether it’s business data, health statistics, or geo-information, you’ll get the skills you need to turn raw numbers into visuals that make an impact.
At Geo-ICT, we’ve developed this course to not only teach you tools but to empower you with skills that are directly applicable in your domain. Whether you’re a beginner or looking to deepen your expertise, our course structure supports a wide range of learning goals.
On day one, you’ll get a full overview of ggplot2 and learn how to work with large datasets using tidy data principles. You’ll start building basic charts like bar graphs and scatter plots using real-life datasets. By the end of the day, you’ll have a solid understanding of how to structure and visualize data with R and ggplot2.
On day two, we go deeper. You’ll learn how to customize your graphs, from adjusting legends and axes to visualizing grouped and categorical data. You’ll also get the chance to work with your own datasets, applying what you’ve learned to projects that matter to you. Throughout the day, we’ll reinforce key concepts with practical exercises that build your confidence and skill.
