Diagram Design vs Data Visualization

Diagram Design

By Cathryn Lavery

Create polished, on-brand diagrams and charts, from flowcharts to org charts and journeys.

Data Visualization

By JR Brugger (Design Workflow)

Design clear charts and graphs that communicate insights without confusion.

Diagram Design

• Draws 45 diagram and chart types, from flowcharts to user journeys and 2x2 matrices
• Matches your brand by pulling colors and fonts from your website
• Redraws existing draw.io, Mermaid, or Excalidraw diagrams in a cleaner style
• Sizes diagrams for docs, slides, social posts, or print
• Exports to PNG or SVG when you ask

Data Visualization

• Recommends the right chart type based on what you're trying to show (trends, comparisons, distributions, relationships)
• Applies design principles that make charts clear and easy to read (proper labels, colors, and minimal decoration)
• Ensures visualizations are accessible to all audiences including colorblind users
• Guides responsive design so charts work on mobile and desktop
• Provides best practices for direct labeling, context, and interactive exploration
