What changes are you trying to make? (e.g. Adding or removing code, refactoring existing code, adding reports)
Added my written critique for one “good” and one “bad” public data visualization in assignment_2.md, including justification (design principles) and concrete improvement suggestions for each.
What did you learn from the changes you have made?
I learned how to evaluate visualizations more systematically
Was there another approach you were thinking about making? If so, what approach(es) were you thinking of?
Yes: I considered choosing examples from a news outlet or academic paper instead of Tableau Public
Were there any challenges? If so, what issue(s) did you face? How did you overcome it?
The main challenge was keeping within the word limits while still giving specific, evidence-based critiques.
How were these changes tested?
NA
