Composition deals with the overall readability and meaning of the project. As noted by Kirk (2016), the topic of composition is divided into project-level and chart-level composition. Select one component of either project composition or chart composition and discuss.
A quality post is more than stating, I agree with you. Maybe you should state why you agree with your classmates post. Additionally, post some examples or find a related topic on the internet or Universitys library and comment on it in the discussion post.
