Data Visualization in R

Create stunning graphics for your Data Science projects

Course details :

A fun, hands-on, and project-based workshop that help students gain full proficiency in data visualization systems and tools. Create compelling narratives by combining charting elements with custom aesthetics under the guidance of our instructors.

The 4-day course follows our learn-by-building approach, in that students are tasked to reproduce a series of plots applying what they’ve learned. While it covers the three main plotting systems in R, its particular focus is on ggplot2 and the additional libraries centered around it that brings interactivity and enhanced aesthetic options to the art of creating rich, powerful visualizations.

Academy Modules


Pproject: Mining Trending Videos on YouTube

  • Hands-on Data Visualization
  • Identifying Temporal Patterns in Trending Videos
  • Combining Aesthetics and Geometries

Learning-by-Building Module (2 Points)

Creating a Publication-Grade Plot

  • Applying what you’ve learned, create an economics- or social-related plot that is polished with the appropriate annotations, aesthetics, and some simple commentary. You may use the same “YouTube Trending Videos” dataset or any other dataset for this practice.

Creating an Interactive Map

  • Applying what you’ve learned, create a web page with an interactive map embedded on it. Use a custom icon for the map markers to represent business locations, and show details about each location pin (“markers”) upon user’s interaction with it.

Workshop Receivables:

  • Workshop Lecturer’s Notes

    Including 2x Course Books (PDF), HTML files, course transcripts (if any).

  • Highly-accelerated Learning

    Learn under the assistance of mentorship of our lead instructor and a band of qualified teaching assistants throughout the 4-day course.

  • Certification of Completion

    Show current and prospective employers that you’ve completed the course with a signed certificate of completion.

  • Quality Learning Environment

    We pay meticulous attention to the logistical details of our workshops: quality audio and visual setups, comfortable sitting arrangements, small group size. Dinners are included for evening workshops.

  • Supplement Materials

    Receive supplement datasets to practice on, reference notes, working files (R Notebook or Jupyter Notebook), and other materials that will help you master the topics.

This workshop is recommended for:

The Programming for Data Science workshop is designed for casual learners, working professionals and non-programmers that are taking their first steps into data science and machine learning.

Students are not assumed to have a working knowledge of R or prior proficiency in statistics / mathematics / algebra. At such the workshop follows a gentle learning curve and emphasize on hands-on, one-to-one tutoring from our team of instructors and teaching assistants.

Consider taking our Intermediate-level workshops instead for more advanced-level materials in statistical programming and machine learning.

Past Workshops in this Series:

Students work through tons of real-life examples using sample datasets donated by our team of mentors and corporate partners. We believe in a learn-by-building approach, and we employ instructors who are uncompromisingly passionate about your growth and education.

Part of the Data Visualization Specialization Track

This workshop is part of the Data Visualization specialization track offered by Algoritma Data Science Academy. Participants are rewarded with a certificate of completion upon passing criteria, and are encouraged to advance further in the respective data science specialization.
