Sometimes the hardest part of creating an effective data visualization isn't the data or the tool — it's knowing what structure fits the story. This guide provides reusable patterns, or design templates, for common analytic goals.
Think of these patterns as recipes: they provide a proven structure that you can adapt to your specific data and audience needs. Each pattern is suited to particular types of analytical questions and goals.

Use color to distinguish before/after states (muted vs. bright)
Add labels or callouts to clarify what changed and why
