The Coursera course focused on data visualization with R is an excellent choice for anyone interested in developing their skills in creating informative and visually appealing graphics for data presentation. The primary goal of this course is to equip students with the ability to produce advanced data visualizations using R, a powerful programming language widely recognized for its capabilities in data science, big data, and statistical analysis. One of the core features of this course is its emphasis on the ggplot2 package, which is renowned for its implementation of the grammar of graphics concept. This approach allows students to craft complex plots with minimal code, adding multiple elements such as lines, equations, points, maps, polygons, textual annotations, and colors effortlessly. The course guides learners through creating these graphics in RStudio, a popular integrated development environment for R. The course is thoughtfully divided into seven sections, progressively building the student’s knowledge and practical skills. By the end of the course, learners will be able to create their own customized graphics, understanding both the theoretical foundations and practical applications of the grammar of graphics in R. **Review:** This course is highly suitable for beginners and intermediate users who want to enhance their data visualization skills. It offers a clear, hands-on approach, with practical exercises that reinforce learning. The focus on ggplot2 and the grammar of graphics makes it easier to understand how to translate data into compelling visual stories. Additionally, the course’s structure ensures a gradual learning curve, making complex concepts more approachable. **Recommendation:** I highly recommend this course for students, data analysts, researchers, and professionals working in areas where data visualization is essential. Whether you are new to R or already have some experience, this course will deepen your understanding of creating elegant and informative graphics. Mastering ggplot2 and the grammar of graphics will significantly improve your ability to communicate data insights effectively. Enroll now to develop your visualization toolkit and bring your data presentations to the next level!
O objetivo do curso é desenvolver a habilidade de produzir gráficos para apresentação de dados e informações usando recursos da linguagem R. A linguagem R, eminentemente uma linguagem de programação voltada para ciência de dados, big data e principalmente processamento estatístico de dados, possui também poderosos pacotes para exploração gráfica de dados. Dentre esses pacotes o principal é o ggplot2 que é fundamentado num conceito de gramática de gráficos, onde o usuário cria uma plotagem escrevendo o gráfico em um código com poucas linhas e adicionando quantos elementos queira ao gráfico (linhas, equações, pontos, mapas, polígonos, textos, cores, etc.). Assim, ao decorrer do curso, subdivido em 7 seções, o aluno será capaz de criar os próprios gráficos conhecendo a gramática de gráficos da linguagem R, trabalhando no software RStudio.
