Data Visualization Overview

A comprehensive set of flashcards covering key vocabulary and concepts related to data visualization, its principles, and effective practices.

Data Visualization

The graphical representation of data to communicate information clearly and efficiently.

Patterns

Recurring relationships or regularities observed in data.

Trends

The general direction in which data values move over time.

Outliers

Data points that significantly differ from the rest of the dataset.

Charts

Visual representations of data using shapes like bars, lines, or points to show relationships or trends.

Graphs

Mathematical or network-based diagrams that show connections or relationships between variables or entities.

Maps

Spatial visualizations that display data geographically.

Dashboards

Interactive interfaces that consolidate multiple visualizations for a quick overview of key metrics.

Clarity

The principle of making the visualization easy to understand and avoiding clutter.

Accuracy

The principle of representing data truthfully without distortion.

Efficiency

The principle of conveying information quickly by highlighting key insights.

Consistency

Ensuring that colors, scales, and units are used consistently across charts.

Comparability

Making it easy to compare data points by aligning charts and using common scales.

Aesthetics

Engaging viewers and enhancing understanding through clean design and purposeful use of color.

Storytelling

Guiding the audience to insight by logically arranging visualizations.

Preattentive Attributes

Visual properties processed in milliseconds to help viewers recognize patterns quickly.

Categorical Data

Data representing distinct categories that are mutually exclusive with no numerical values.

Ordinal Data

Data similar to categorical data but with a clear order or ranking.

Quantitative Data

Numerical data that can be measured and aggregated.

Sequential Color

A color scheme ordered from low to high, typically in shades of a single hue.

Diverging Color

A color scheme that uses two colors with a neutral midpoint, representing ranges of a measure.

Categorical Color

Different color hues used to distinguish individual categories.

Highlight Color

Color used to draw attention to specific data points without alarming the viewer.

Alert Color

Bright colors intended to draw immediate attention to important information.

Color Vision Deficiency (CVD)

Difficulty in distinguishing colors, particularly red and green, affecting visual accessibility.
