課程介紹

Course Objectives

This course is designed to develop the skill of efficient graphic language, where efficiency is defined as the data information delivery that is self-contained, concise, and non-distorting. The programming language is mainly based on R, with a little bit of Javascript toward the end. Though there is no computer programming knowledge required, basic R knowledge will help (the ebook, R for Data Science, would be a good start). By the end of the course, students who learn well should be able to design professional dashboards like the Big-Mac index from 《the Economist》 Magazine . (The course will be taught in mixed language–Chinese and English, but mainly in English, since English is an important skill for being a good programmer.)
