✅ Show Change Over Time (Before vs After)

Like your reading proficiency chart. Use curves or bars to show movement, not just static numbers.

✅ Compare Against Targets

Not just “78% improved” — show how that compares to a goal.

✅ Use Multiple Visual Types When Appropriate

Bar + line + funnel + heatmap can all coexist.

✅ Add Callouts and Narrative Labels

A legend alone isn’t enough — add text boxes that explain why changes matter.

✅ Make It Graphic-Rich, Not Spreadsheet-Like

White backgrounds, subtle gridlines, big text, bold lines.
