The public website of this course introduces the learning path of data graphics expression, design judgment and R tools. For those who wish to understand data representation, it provides a learning material that can be explored further. You can read the course syllabus first to determine whether the content is relevant to your question, and then decide whether to enter the explanations and exercises on the original site.

The course site documents Georgia State University's 2022 summer courses. The author's personal website currently lists the institution where he works as Georgetown University in Qatar. The teaching year of the original course and the author's current appointment are retained separately: old courses cannot be rerecorded as being offered by the current institution, nor can current enrollment or service arrangements be inferred based on this.

If you want to further ask "How can I express my data more clearly", you can first write down the audience, data source, current reading difficulties and methods you want to know. Knowledge consultation is the sorting out of problems; whether professional services are needed, who will undertake them, and how to support them will be confirmed later.
