Notes on Data Visualization Lecture by Federica Fragapane

Introduction

• Speaker: Federica Fragapane, independent information designer.
• Background: Freelance work in data visualization for various clients including UN, Google, BBC.
• Education: Communication design at Politecnico di Milano, focused on information design.
• Thesis: Data visualization project on organized crime in Northern Italy.

Career Path

• Worked at a design studio called Akward in Milan and New York.
• Transitioned to freelancing in 2015 for career exploration.

Scope of Work

• Data Visualization Goals:

  • To visually translate complex data into understandable visual formats.
  • Projects vary in complexity based on context, audience, and purpose.
  • Strong focus on creating connections between data and readers.

• Examples of Work:

  • Collaborations with cultural supplements, children’s books, Google Trends, BBC on space junk.
  • Visualized the menstrual cycle for Scientific American.

Design Process

• Three Main Phases:

  1. Selection of topics, sources, and stories.
  2. Data extraction, organization, and analysis.
  3. Designing visual representation of data.

• Tools Used:

  • Primary tool: Adobe Illustrator for static visualizations.
  • Other tools: Photoshop, QGIS (for maps), RawGraphs (for transitioning data to visuals).

Lecture Focus: Using RawGraphs

• Demonstration on creating visualizations using a dataset of annual working hours by country.
• Importance of contextual information (e.g., GDP per capita, population).
• RawGraphs allows for easy data input and visualization transformation.
• Examples of visualizations created include:
  • Bar charts.
  • Bubble charts.
  • Linear dendrograms.

Designing with Aesthetics

• Importance of aesthetics in engaging readers, not just for visual appeal but for enhancing communication.
• Preference for organic shapes when representing human-related data.
• Emphasis on clear legends for understanding the visualizations.

Color Choices in Visualization

• Recommendations for using limited color palettes to aid in color distinction for all readers.
• Importance of contrasting colors and the use of gradients for depth.
• Tools for selecting color palettes (e.g., Pinterest for inspiration).

Feedback and Iteration

• Importance of seeking feedback from non-experts to gauge clarity and understanding of visualizations.
• Refinement process often involves multiple iterations to improve clarity and presentation.

Conclusion

• Encouragement for students to engage with data visualization, highlighting the potential for exploration and creativity.
• Invitation to join the course for deeper insights into data visualization techniques.
