Simple Clean Flat Design

A simple yet clean flat design.
Place people and icons drawn with uniform black outlines, and use pastel-style accent colors in some areas. Uniform line thickness as much as possible for a modern look.
Emphasizes rounded shapes and a soft impression.
Structurally focused on diagrams (e.g., Venn diagrams, bar graphs, speech bubbles, etc.), it features an approachable tone for students and younger audiences to view in materials and social media.
The design features plenty of empty space, focusing on visibility and balance.
