Section 3.6 Checklist

When creating a visualization, have you:
  • Started by visualizing your data (not relying only on summary statistics)?
  • Chosen a plot type that matches your goal?
  • Confirmed whether your data are raw counts (geom_bar()) or pre-summarized values (geom_col())?
  • Clearly defined aesthetics (x, y, color, shape, fill) and mapped them intentionally?
  • Added informative labels using labs() (title, axes, legend)?
  • Adjusted the layout for readability (e.g., coord_flip(), facet_wrap())?
  • Considered whether trend lines, error bars, labels, or reference lines would help communicate the story?
  • Checked that the visualization is interpretable without additional explanation?
  • Asked: What question does this plot help answer?
