    Study Notes

    MCQ Component 1: Basics

    • Data visualization (DV) is needed because humans process visual information easily.
    • Complex analytics are hard for decision-makers to understand.
    • DV condenses large amounts of information into smaller areas (e.g., dashboards).
    • Dashboards allow for interactivity.
    • Relationships, comparisons, trends, and focus areas are highlighted.
    • DV improves insights.
    • The key theoretical concepts for DV include:
      • Need for data visualization
      • Steps in data visualization
      • Points to keep in mind
      • Design principles
      • Chart types and their use.

    Why Data Visualization (DV) is Needed

    • Humans process visual information efficiently.
    • Decision-makers often lack the ability to grasp complex analytical data.
    • Data visualization allows for efficient presentation of large amounts of information in a concise manner.
    • It facilitates interactivity through dashboards.
    • Relationships, comparisons, trends and areas of focus are easily discernible.
    • DV ultimately improves insights.

    Data Visualization & Visual Analytics

    • Data Visualization and Visual Analytics are intertwined concepts.
    • Visual Analytics incorporates several key perspectives, including Interactive, Informative, Infographic, Graphical, and Analytical.

    Steps for Data Visualization

    • Acquire: Obtain the necessary data.
    • Parse: Structure the data to understand its meaning.
    • Filter: Select relevant data for analysis.
    • Mine: Apply statistical and data mining methods to discover patterns and contexts.
    • Represent: Choose an appropriate visual representation (e.g., bar chart, list, or tree).
    • Refine: Enhance the visualization for clarity and visual appeal.
    • Interact: Allow for data manipulation and feature control.

    Example Steps for Data Visualization (DV)

    • Scenario: Create a dashboard for a company's CMO using historical sales data.
    • Steps: Acquisition, parsing, filtering, mining, representation, and interaction.

    Keep in Mind: Context, Audience, Goal

    • Context: What questions need answers? Gathering necessary background information.
    • Audience: Who are you presenting to? Their potential biases and how they will use the DV.
    • Goals: Transforming business questions into visualization tasks. Prioritizing crucial information.

    Audience Attention

    • Fundamental concepts for designing visuals to ensure audience engagement.
    1. Pre-attentive attributes.
    2. Tufte Guidelines.
    3. Gestalt Principles.

    Gestalt Principles

    • Good Figure: Groupings perceived as single units.
    • Proximity: Grouping objects close together.
    • Similarity: Grouping similar objects.
    • Continuation: Objects perceived as continuous.
    • Closure: Visual connections between separate elements.
    • Symmetry: Symmetrical arrangement of objects.
    • Common Fate: Objects moving in the same direction are related.

    Tufte's Principles

    • Graphical Integrity: Visual representation accurately portrays data.
    • Maximise Data Ink: Minimize non-data elements in the graphic.
    • Reduce Chart Junk: Eliminate unnecessary elements.
    • High Data Density: Shrink Principle: Allowing presentation of many data points on the same chart with less clutter.
    • Small Multiples: Use multiple charts to see how data varies.

    Visual Types

    • Provide various chart types (scatter plot, column chart, bar chart, line chart) for displaying data relationships and distributions.
    • Use of chart types helps in displaying data effectively for different types of data.

    StoryTelling & Feedback

    • Storytelling structure: Big Idea, Beginning, Middle, End, and Narrative Framework.
    • Feedback sources for refining the story: Colleagues, Clients, and Third parties.

    Good or Bad Dashboard Design

    • Dashboards should be clear, clean, and easy to understand, with sufficient data presentation in each graph.
    • Visual elements shouldn't distract from the information presented.
