“The learning paths on Dataquest are incredible. They give you a direction through the learning process - you don’t have to guess what to learn next.”
Otávio Silveira
Data Analyst @ HortifrutiPath overview
In this path, you will gain experience in manipulating, comparing, and presenting compelling and actionable data and you’ll discover the best methods for visualizing data using line graphs, histograms, bar charts, scatter plots, and more. You’ll learn how to use R programming and ggplot2 to create meaningful data visualizations. Ggplot2, which is a part of tidyverse, is an R package for data visualization. It’s one of the most versatile and easy-to-use tools for creating elegant graphics using R, and it’s the main focus of this path.
Best of all, you’ll learn by doing — you’ll write code and get feedback directly in the browser. You’ll apply your skills to several guided projects involving realistic business scenarios to build your portfolio and prepare for your next interview.
