Syllabus: Interactive Visualizations

This course is designed for students with a basic familiarity with R and some experience with data analysis and data manipulation. In less than 90 minutes of instructional time, students learn how to create dynamic visualizations in R and embed them into websites or host them on other sites. This course also teaches students how to collect data from different websites and manipulate that data so it can be visualized in R.

By the end of this course, students will be able to:

  1. Create interactive visualizations
  2. Publish dynamic graphs to websites
  3. Collect and manipulate data from almost any website
Assessment:
  1. Concept reviews: these are comprised of short five question quizzes that cover the most important concepts and ideas in each lesson. They encourage holistic understanding and are multi-faceted question types (i.e. drag and drop, fill-in-the-blanks, matching, etc).
  2. Exercises: these are additional videos that cover the coding functions in the instructional video in more depth. They are project-based and include coding templates for students to strengthen their skills outside of the course.
Materials provided:
  1. Accompanying PDFs to use as reference materials
  2. R code templates from the instructional videos and exercises
  3. Data sets used in the instructional videos and exercises
