Study Notes
Data Visualization
- The act of making something visible to the eye.
- Visual display of information, usually in a multi-level format including conveying information through the graphical representation of data.
Data Visualization Design
- Speak to end-users to understand who will use the visualizations, why they need the information, and what devices will be used to access the visualizations.
- Select the right type of data visualization, such as charts, graphs, maps, dashboards, tables, and infographics.
- Create low-fidelity sketches, wireframes, and prototypes before committing to visuals with a robust, coded tool.
- Uncover critical elements and identify the requirements that are necessary for decision-making.
Types of DataViz
- Infographics
- Charts
- Graphs
- Tables
- Maps
- Dashboards
Infographics
- Turn complex data into easily digestible visual designs combining good design and illustration with salient data to present complex information in an engaging way.
- Infographics help us remember and understand information.
- 30 times more likely to read an infographic than a text-based article.
- People remember 65% of the information on the pictures they see.
- Easily understood through visual information.
Infographic Uses
- Illustrate data
- Simplify complex information
- Compare two or more things
- Make patterns and relationships visible
- Raise awareness
- Enhance stories
- Improve brand visibility
- Make information memorable
- Are shareable
- Can be repurposed for print
Creating an Infographic
- Research the topic
- Gather data
- Organize the data into charts, graphs, maps, timelines, etc.
Infographic Design
- Use graphical visualizations to show patterns and trends.
- Use color to draw attention to specific sections.
- Create a structure and flow that is easy to follow.
- Use engaging and attention-grabbing images and symbols that relate to the topic.
- Use small amounts of text.
Information Graphics (Infographics)
- Present information in a visual and appealing way.
- Simplify or summarize complex information and large amounts of data.
- Make large amounts of complex data easily understandable at a glance.
- Compare two or more different things.
- Make patterns and relationships visible.
- Communicate a specific message.
- Monitor changes in variables.
- Engage our brains.
Visual Thinking for DataViz
- Good DataViz excites the audience's sense of sight.
- Our brains process up to 83% of information by looking at it.
- Don’t overload your viewers’ senses!
Gestalt Principles of Visual Perception
- Proximity
- Similarity
- Enclosure
- Closure
- Continuity
- Connection
Cognitive Load and DataViz
- Cognitive load = the mental effort used in our working memory to process visual elements.
- Every element added to a page takes up cognitive load from the audience.
- Only add visual elements that add informative value - declutter!
- Avoid unnecessary cognitive load.
- Be mindful of the data-ink ratio - devote the largest possible share of a graphic’s ink to data.
- Maximize the signal-to-noise ratio – the signal = information, the noise = elements that don't add to or distract from the message.
Clutter
- Adds unnecessary cognitive load.
- Makes it difficult to process information.
- Can cause the audience to disengage.
Clever Use of Colors, Size, and Position
- Leverage size and/or color to highlight important parts.
- Use color sparingly and intentionally.
- Use visually appealing techniques to lead the viewer’s eye through the infographic, such as using a zigzag “Z” pattern.
Legal Use of Graphics
- Copyright vs. Royalty-free images.
- Ensure legal permission to use graphics.
- Copyright infringements can be costly.
- Some online images are free to use (e.g. those without explicit copyright indicators).
What is Tableau?
- A Business Intelligence tool that enables you to use your data to ask and answer detailed questions.
- Used to tell visually compelling stories to offer insight, understanding, and intelligence to support business decisions.
