Study Notes

Data Visualization

Hierarchical data structures, such as organizational charts or decision trees, are best displayed using a Sankey diagram.

Data Visualization Over Time

Line charts are most suitable for representing changes in data over time, allowing viewers to observe trends and patterns easily.

Choropleth Maps

Choropleth maps are used to represent geographic distributions using color variations, making it easy to visualize and understand the data.

Designing Interactive Visualizations

A key consideration when designing interactive and dynamic visualizations is to prioritize simplicity and ease of use.

Data Visualization Dashboards

A dashboard refers to a dynamic, interactive display of key performance indicators.

Common Pitfalls in Data Visualization

Chartjunk is a common pitfall in data visualization that involves distorting the representation of data to emphasize certain aspects.

Effective Storytelling in Data Visualization

Using clear narratives and annotations is essential for effective storytelling in data visualization.

Small Multiples in Data Visualization

An advantage of using small multiples in data visualization is that it simplifies the overall design.

Color in Geographic Data Visualization

Color plays a crucial role in geographic data visualization, helping to convey data patterns and variations.

Effective Dashboard Design

A fundamental aspect of effective dashboard design is to ensure a clear hierarchy of information.
