Master Data Visualization
with ggplot2
An all-in-one, interactive online course designed to make you a ggplot2 dataviz expert.
😱 Stuck on beginner mode?
ggplot2 is the ultimate tool for creating graphs with code. So powerful that Python made a copy of it!
Yet, reaching a professional level is hard. You have to understand syntax tweaks, navigate a jungle of extensions, learn about different chart types, and master the fundamental principles of dataviz.
It takes time and effort, and without proper guidance, your charts might never reach that stunning, polished look. 😔
🔥 Let's make insightful charts
This online course packs everything you need to know about ggplot2 and data visualization.
After just a few hours, you’ll know what to draw and how to draw it, creating stunning graphs that people actually want to read.
Sure, you could keep copy-pasting code from ChatGPT. But it won't teach you the secret sauce to design a great chart and you will forever struggle with the last bit of polish that makes your work standout.
Instead, you could just learn everything in a few hours here thanks to our course!
It's time to transform bland, default charts into stunning, insightful masterpieces!
When I'm asked to recommend examples of beautiful charts designed with the R programming language, Cédric's work is invariably the first that comes to my mind. I think that this is all I need to say about how much I admire his work!
Cédric’s R workshops are an insightful and engaging way to learn how to code and create effective visualizations—clear explanations, beautiful examples, and practical takeaways throughout.

Elevate your storytelling techniques by crafting charts that not just show data—but guide your audience with clarity 🎯
Clear and well-placed text elements make your visualizations more engaging, helping viewers understand key insights at a glance.
ggplot & dataviz concepts you'll learn:
Plot Composition
This module teaches you how to arrange multiple plots into a coherent narrative. You'll learn about small multiples, advanced faceting techniques, and multi-plot layouts to structure visualizations effectively.
Learning to structure multiple plots effectively will transform your visualizations into a compelling narrative 📚
Mastering plot composition allows you to showcase trends, compare categories, and communicate complex insights with clarity.
ggplot & dataviz concepts you'll learn:
Visualizing Spatial Data
This module covers the essentials of working with spatial data in ggplot2and sf. You’ll learn how to create maps, customize spatial layers, and fine-tune geographic visualizations for effective storytelling.
Building spatial visualizations helps you explore geographic insights and reveal meaningful patterns 🗺️
Whether you’re analyzing geographic trends or presenting location-based insights, learning how to create well-designed spatial visualizations allows you to add depth and clarity to your data.
ggplot & dataviz concepts you'll learn:
Interactivity & Animation
This module introduces interactive and animated visualizations to make your data more engaging. You’ll explore quick interactive plots with plotly, more refined interactive charts with ggiraph, and dynamic animations using gganimate.
Crafting interactive and animated visualizations empowers your audience to explore details and engage with your findings 🕹️
Interactive and animated charts make your insights more intuitive, helping users explore data in a way that static plots simply can’t.

💎 You'll Make Great Charts!
We've built hundreds of stunning charts, and we'll help you do the same. Real projects, hands-on exercises, and a discord channel to post your work and get feedback.
Yan delivered an exceptional talk on Data Visualization at our MIT research centre, and we gained a tremendous amount of insight from his expertise!
His tools, workshops, and training resources are invaluable for anyone looking to enhance their data visualization skills, and we highly recommend exploring them.
It was such a joy working with Cédric on his Pearson live trainings hosted on O’Reilly!
Drafting and hosting a 2-3 hour live training is no small feat, and Cedric was adept at curating a strong curriculum and being attentive to his student audience. His teaching style was impactful, and he brought creativity and enthusiasm to every planning call and training.
👋 Hi, we're Yan and Cédric!
Yan Holtz is a data visualization expert and software engineer with 10 years of experience helping researchers and companies craft their charts.
He’s also the creator of popular sites like Data-to-Viz and the R Graph Gallery, so chances are, you’ve already benefited from his work without even knowing it!
Cédric Scherer is an independent data visualization professional. As a consultant, designer, and developer, he specializes in helping clients communicate insights effectively through engaging data-driven visuals, reports, and presentations.
Cédric regularly teaches data visualization principles and hands-on data science with R and the tidyverse. He has been an invited instructor and speaker at conferences such as RStudio::conf and Posit::conf, Data2Speak, and Outlier, and has delivered tailored trainings to teams at Fannie Mae, Supercell, Charité, the Robert Koch Institute, and others.

Yan has developed some of the most valuable resources for my courses, now cited as seminal references.
Thanks to Yan’s clear explanations and well-structured code, even beginners can effortlessly replicate graphics in R. A tour de force!
Yan’s gallery and Cédric’s tutorials were the two most important resources for me when I started learning how to create data visualizations with R.
These two experts are teaming up for a dataviz course? I can’t wait to see the outcome!
I attended both of other Yan's courses, productive-r-workflow and matplotlib-journey, and they were excellent.
Clear, well-structured, and highly insightful. I highly recommend them and can't wait to follow this one too!
I’ve taken some of Yan’s other courses before — they were super well structured and especially helpful for mastering Quarto tips.
They also inspired me with new ways to visualize data and showed just how much is possible with R. No doubt this new course on data visualization will be amazing too!
Cédric’s work is a great inspiration for those making graphs with R and ggplot2 and beyond. And he doesn't keep his data vizardry a secret, he shares it with others!
Cédric's open communication, creativity and technical skill significantly enhance the overall quality of our data communications.
I wholeheartedly recommend Cédric and look forward to continuing our relationship with him in the future.
Cédric's expertise in data visualisation is of great value. He has a talent for making complex concepts accessible and inspiring and received overwhelmingly positive feedback from our participants. His contributions were a highlight of our programme!
Cédric transformed our report with his amazing data visualizations. He turned complex data into clear, eye-catching graphics that told our story perfectly. His mix of technical skill and creative design made our findings easy to understand and visually striking. Working with Cédric was a pleasure, and I highly recommend.
Cédric's has a gift for seeing the story in numbers and creating graphics that communicate clearly and beautifully. His expertise helped our report stand out and engage our community in ways we didn't expect. Cédric is professional, talented, and truly understands how to make data speak to people.

A while ago I reluctantly decided that there is no rationale for me to learn ggplot. I still believe so. And yet, here I am, desperately resisting temptation. Two guys I admire, and a course that looks brilliant. Sigh.
